PRX-front-543Ever since I started this blog, I’ve talked about attenuators, and how they’ve enabled me to get tones out of my amp at reasonable volume levels that I could only previously get at super-high volumes. But before I get into the discussion part of this article, take a listen to this clip (it’s the same clip I recorded with my previous article on the Mullard ECC83):

Here are some details about the recording:

  • I plugged directly into my Aracom VRX22, which then fed into my Aracom PRX150-Pro, then out to a custom 1 X 12 with a Jensen P12N
  • The amp was in the drive channel with master at 6, volume (gain) at 6, and tone at 6 (the tone on this amp adds a little gain as well as an edge)
  • The PRX150-Pro was set at maximum attenuation
  • Volume-wise, this was talking conversation level!!!
  • No EQ was applied to the guitar – what you’re hearing is the raw tone.

With respect to “maximum attenuation,” I was in variable mode with the variable sweep pot all the way to its left extent. I shared my amp and PRX settings with Jeff Aragaki this morning, and he estimated that the output power was approximately 0.04 Watt!

Many people are apt to talk about how the speaker needs to move air, and that an attenuator doesn’t allow that to happen. But that clip simply demonstrates that with the right combination of equipment – and in my case, also a great set of tubes – you don’t necessarily need that speaker cone breakup to get great tone for recording purposes. Yes, SPL’s do play a big role in your overall tone, but to be able to achieve the kind of tone I was able to get at that very low volume level is nothing short of amazing!

So what about an attenuator being life-changing?

Maybe that’s a bit strong of a phrase, but ever since I’ve been using attenuators, and especially since I’ve gotten my Aracom PRX150-Pro, I’ve been able to explore tonal territory that I could previously only achieve using pedals – and only simulating at that! Take overdrive pedals for instance. If you’re a regular reader of this blog, you know I’m crazy about them. I probably will still be nuts about overdrive pedals, but there’s one thing an overdrive pedal can’t do that an attenuator allows me to do, and that’s to get the thick, natural overdrive tone of my amp. Don’t get me wrong, I still use them, but I use them now more for tonal accents to my drive tone rather than giving me my drive tone. That’s very profound; especially for an overdrive pedal freak like me!

Here’s a good example that I just recorded. This clip is part of a new song idea I’ve been playing around with. Setup is pretty much the same as above, but for the rhythm, I’m running Strat into my Kasha overdrive pedal to get a jangly, crisp tone. The lead is Goldie plugged straight into my VRX22. I did mix and do a simple master on the recording, but the guitars were all recorded raw, with no EQ. In my DAW, I added some reverb to both parts and a touch of delay to the lead, but that’s it.

Speaking of pedals, since I’ve started using a high-end attenuator (there are others such as Alex’s and the Faustine Phantom), I’ve actually started using pedals in general much less. I’ve really relying on the natural tone and sustain of my amp. For instance, I’ve found that I’ve only been using reverb in the studio. When I play out, I just don’t bother. In fact, for the last few weeks, I’ve only been taking two pedals to gigs with me: My BOSS TU-2 Tuner and my VRX22’s channel switcher. Same goes with my Reason Bambino.

Life-changing? Probably not, but definitely approach-changing. I may personally endorse the PRX150-Pro, but there are others out there. If you really want to hear what your amp has to offer when it’s fully cranked with the power tubes glowing, then you owe it to yourself to get a good attenuator!

Mullard Zaerix 12AX7Conventional tube-amp wisdom states that you get the most bang for your buck by replacing your pre-amp tubes. I’ve been a believer of this for quite awhile, and have tried out all sorts of pre-amp tubes in my amps over the years. A couple of days ago, I wrote that I had installed a new Mullard ECC83 (12AX7) into my Aracom VRX22. This particular Mullard is a Zaerix-labled ECC83 that probably came from the GDR (I didn’t look at the numbers – I really don’t care, for that matter). All I know is that it made a HUGE difference in the way my amp sounds. The overdrive instantly became smoother and more focused without top-end artifacts, and the notes are still very defined even at high overdrive settings on my amp.

The clip below says it all. I recorded this clip playing in the bridge pick up of Goldie, plugged straight into the VRX22, which then fed into the ever-so-awesome Aracom PRX15-Pro attenuator. The amp’s master, tone, and volume knobs were all set at 6 (about 2pm on the amp), and the clip was recorded at bedroom level!

To my ears, the VRX22 sounds like a much bigger amp than its 22 Watts! I’m really in tonal heaven right now!

I was feeling like crap today, but still accompanied my friend, Jeff Aragaki, to go to the offices of Guitar Player Magazine, which just so happens to be local to us in the Silicon Valley. Nested in an office building near the heart of San Bruno, CA, the office itself is rather unassuming, though there are tons of pictures hanging on the wall of great musicians from over the years. Very cool.

Like I said, it looked like your typical office, replete with cubicles… Then you see all the guitar cases in the cubes, and the amps stacked along walls, and effects in various states of disassembly on desks for evaluators to examine. Moving to the back of the office, is an area filled with boxes of gear waiting to be reviewed. Had I died and gone to heaven? 🙂

Jeff invited me along to help him show some of his equipment to the GP folks. We were supposed to meet with one of the editors, but unfortunately, because of the SF Bay Bridge closing, he couldn’t make it to the meeting. Instead, we were greeted by Reggie Singh, who is the marketing and ad sales guy for the mag. Very cool dude. He gave us a tour of the office, and let us get some back and upcoming issues of the mag, plus some very cool swag (I got this GREAT coffee table book on Gibson guitars). But the highlight of the day was going into the GP test studio where I got to demo the PRX150-Pro for Reggie.

For the demo, I played a ’59 Les Paul Reissue with the fat 50’s neck and light, mahogany body. OMG! Reggie said that guitar was the one everyone uses to test gear. The way he said it was so non-chalant, as if that was a beater guitar (mind you, it was great shape)! You gotta love being able to work at a guitar magazine! Anyway, we demonstrated the features of the PRX150-Pro through a Dr. Z Remedy. That’s a 40 Watt, quad 6V6 tone beast that was absolutely incredible! Very simple control layout – just single bank of a few knobs, and it had such a sweet tone! I think I’m going to have to review this one… 🙂

Going to that magazine office was an eye-opener… There’s A LOT of gear out there! You don’t fully realize it until you go to a place like this where people’s jobs are to evaluate it. It’s not like a store where things are on display. In fact, several times, Reggie told us, “Hey, if you want to plug something in, please feel free.” Damn! I could spend a whole day there and not make a dent in all the gear that’s in that office.

That was truly an adventure of magnificent proportions!

Just put in a re-labeled 1960’s-era Mullard ECC83 into my Aracom VRX22 this afternoon. I had a JJ 12AX7 in there, and make no bones about it; that’s a great pre-amp tube. But the difference in tone between the two is immense. Where my JJ had a great tone, one thing that I noticed was that the highs tended to be rather harsh when the tube was overdrive, and I found myself turning my Tone knob left of center – a lot – to bleed off some of the highs.

But after I installed the Mullard, I was absolutely blown away! The overdrive seemed so much more focused, with zero high-end harshness. It was some of the smoothest overdrive I’ve heard, and definitely the smoothest the VRX22 has sounded since I got it. That’s saying quite a bit because I love the tone of this amp immensely, even without the NOS Mullard. Which brings me to the crux of this entry…

As a tube amp aficionado, I’ve gone through lots of pre-amp tubes, and almost invariably, I’ve gravitated towards NOS tubes to get the tone I like. Some people I’ve spoken to say it’s all hype but, at least to me, it’s not. I suppose for some types of tubes, there’s not much of a difference. For instance, I almost invariably use JJ’s for power tubes because they just sound great to me. They’re well-made, and run pretty hot, and they break up nicely.

But with respect to pre-amp tubes, I’ve found a marked difference between NOS and new tubes. I love Mullard and JAN Phillips tubes for pre-amp tubes. They’re just so smooth sounding, smoother than all the new make tubes I’ve played. Plus, they were made during a time when most electronic devices were run with tubes, so the build expertise, equipment and materials for making tubes was abundant. According to my friend Jeff Aragaki of Aracom Amps, the alloys used in NOS tubes are not as readily available nowadays, and that could account for the difference in tone. Not sure if this is true, but it certainly makes sense. The only drawback is the price. That Mullard sells for $129 retail, and that is by no means inexpensive.

But I look at buying NOS tubes very much like buying a great pair of shoes. For instance, I spend almost $200 a pair for my everyday shoes. These are absolutely comfortable, and not only that they last a long time because they’re constructed so well. In fact, it takes me about 4-5 years to really wear them out. This in contrast to lower priced shoes that I’ve worn out within a few months. After a long period of time, I’ll spend more on the cheap shoes. A better case is my father. His shoes cost at least $500. But they last almost 20 years! He just gets them resoled every few years until the shoe repair guy says that it’s not worth it.

NOS tubes are similar. I’ve had the same NOS tubes in my Hot Rod Deluxe for almost five years, and they still sound great! I play that amp a lot. On the other hand, the new Tung-Sol tubes I put in another amp lasted all of two months before they started to lose their character, with one becoming microphonic. Granted, they’re fairly inexpensive tubes and they sound great, but if I have to shell out $25 every couple of months, that starts to add up. NOS tubes, especially the mil-spec tubes that I prefer were made for military usage, which means they had to be well-built and durable. That’s a huge advantage NOS tubes have over newer tubes.

Jeff also shared a story with me today about a friend of his who used to be stationed on an aircraft carrier. He was telling Jeff that when the ship replaced electronic components, they’d dump boxes of tubes – good ones, mind you – over the side of the ship. So the ocean has NOS tubes littering its bottom.

In any case, please do not just take me at my word! 🙂 This is simply my perception based upon my experience. In the end, as I am often apt to mention, you’re judge of what sounds pleasing to you. So only buy what makes sense to you!

For a long time, I’ve had this thing for getting a big guitar sound in my recordings. I’ve done a bunch of different things like doubling, overdubbing, signal splitting between two amps, and the like. But recently, I got a couple of pieces of gear that is allowing me to explore yet another way to get a big guitar sound: Re-amping. Re-amping is essentially taking an already amplified guitar signal, and running it through another amplifier. This is not like adding a gain stage because that usually involves multiple pre-amp sections. With re-amping, you’re building on a fully amplified signal that has passed through the power tubes. The result is VERY different in tonal character from just moving the signal through another gain stage.

There are lots of ways to re-amp, so I won’t go into a lot of detail. But I will share how I do it. Ever since I got my Aracom PRX15-Pro, I’ve been contemplating this very thing because of its line out which could be used in a variety of ways; such as running the signal into a PA (since it’s unbalanced, you need a DI box), or taking that line level, and running it into another amp to re-amplify the signal yet again. The cool thing about the PRX150-Pro is that I can simultaneously run an output to a speaker, then the amp that’s doing the re-amping can also have it’s own audio output.

Now here’s something even more cool! I have a Reason Bambino, which also has a line out. It’s a balanced line out, so it can go directly into a board, and doesn’t need to be hooked up to an external cab. The tone coming from the line out of the Bambino is very nice. I suppose that I could’ve miked the Bambino from another cabinet, but I did want to test the line out.

In any case, here’s a diagram of how I had everything hooked up:

VRX22-ReAmp

In a nutshell, I plugged my guitar directly into my Aracom VRX22, which ran into the PRX150-Pro. I hooked up an external cab to the attenuator, placed a mic in front of the cabinet that ran into Channel 1 of my audio interface. Then, I ran the line out of the attenuator to the input of the Reason Bambino. From there, I went directly from the Bambino into Channel 2 of my audio interface.

I set up a clip from a song I wrote and added two tracks that took input from the two channels. I also panned Channel 1 full left and Channel 2 full right. Once I had the levels worked out, I recorded a solo over the existing music. Once the recording was finished, I took the Bambino’s signal slightly out of phase with Channel 1, to make it sound like two guitars are playing simultaneously. The effect is totally cool, and it creates a very in-your-face, big guitar sound! Here’s the clip:

Note that this is a kind of a different way to employ re-amping, which basically runs two amps in a series then out a single output. The way I employed it, the re-amped signal is a component of the overall package.

Aracom Amps VRX18 18 Watt Head

Aracom Amps VRX18 18 Watt Head

I’m falling in love again with my Aracom VRX18. This was the amp that first got me introduced to Aracom and my good friend Jeff Aragaki. My amp is actually a tweaked version of the stock VRX18 as it sports an EZ81 tube rectifier, plus a tweaked circuit that adds a bit more sag and sustain. The result is just a gorgeous overdriven tone that really brings out the best of the EL84 power tubes.

One thing about EL84 amps is that if they’re done right, they have a distinctive overdrive tone that creates a subtle top-end fizz when they’re overdriven. I’ve played others that drive the power tubes too much, and they sound very harsh and incredibly compressed. Jeff did this amp right, and while the power tubes do indeed compress a bit, the overdrive tone retains its open character, while adding that nice top-end fizziness that EL84 amp lovers have come to appreciate.

The clip below is an excerpt from a slow blues song I wrote. It features my beloved Goldie plugged straight into the Aracom VRX18, and it also features the insane Aracom PRX150-Pro attenuator! Believe it or not, the amp was recorded at just above loud conversation levels! We’re talking less than 1/10 of a Watt, and the amp still retains its tone and dynamics! Anyway, here’s the clip:

Aracom Amps VRX18 18 Watt Head

This morning, the guy who’s painting my house came into my garage/studio to ask me a question, and being a guitar player himself said, “Dude… you have a great setup.” So the conversation turned to my favorite topic, and of course, that involves talking about guitar gear. 🙂 During the course of our discussion he talked about how he loves Vox amps, and so I demonstrated my Aracom VRX18, which is actually based upon a classic Marshall 18 Plexi, but it had EL84’s. I wanted to give him a reference tone. He just smiled and said, “That’s yummy.”

He had to get back to work, but after not playing that amp for awhile (probably a couple of months), I forgot how much I love its tone. My VRX18 is quite special in that it’s a custom VRX18 that has a tube rectifier, which is an option when you get one of the VRX series amps. Jeff has it tweaked quite nicely, and the amp has tons of sustain, and gorgeous sag without getting mushy and compressed when driven. That’s probably a reason why I haven’t really used EL84 amps that much. My experience has been that they compress a lot when they’re driven hard.

But not this one… Jeff also adjusted the extra gain channel so it wouldn’t compress the power tubes too much. You get lots of dirt, but you maintain the clarity of your notes. This is a great little amp! In any case, I recorded a clip where I have the Master at 3 o’clock, and the Volume at 2 o’clock. That produces some serious grind, but as you’ll hear in the clip, there’s very little compression.

The drive tone the VRX18 produces is absolutely magnificent! When I recorded the clip, I couldn’t believe all the overtones and subtle harmonics that the amp was producing! Jeff really got the tone nailed with this amp!

In addition to the amp, I played through Goldie, running her straight into the amp, then through the insanely transparent PRX150-Pro attenuator set at variable attenuation mode at about 3 o’clock, then into a custom Aracom 1 X 12. Output volume was just yelling level. 🙂

Here’s a list of the Aracom VRX18’s features as a review:

– Channel 1: Volume and Tone Controls
– Channel 2: Volume and Tone Controls
– Master Volume Control (PPIMV)
– On/Off Switch
– Indicator Lamp
– Hi/Low B+ voltage switch (18/9 watts)
– (2) EL84 Power Tubes
– (2) 12AX7 & (1) 12AT7 Preamp Tubes
– Cathode Biased Power Tubes
– S.S. Rectifier with “sag” circuit
* EZ81 Tube Rectifier – Optional
– Custom Heavy Duty Aluminum Chassis
– Custom “Black” Plexi Front and Back Panels
– ARACOM Power Transformer: hand-wound and interleaved
– ARACOM Output Transformer: hand-wound, interleaved on a paper bobbin
– 4, 8, 16 ohm Speaker Jacks
– Detachable Power Cord (IEC320-C13 Socket)
– External Fuse Holder
– Custom Turret Board (G-10/FR4 Flame Resistant)
– Handwired and Handcrafted in the USA.

This little tone beast is such a value as well! At $895 for the head, it’s an absolute steal, and a real hidden gem in the boutique market, as is the VRX22, which is based on 6V6’s.

Aracom Amps PRX150-Pro AttenuatorAracom Amps has just posted a page on their site which features Gene Baker – luthier of the famed Baker Guitars and now of Fine Tuned Instruments producing “B3” guitars – demonstrating the transparency of the Aracom PRX150-Pro Attenuator at various attenuation levels.

Gene has also provided commentary on the recording and how no EQ adjustments were made to the amp – even down to bedroom levels! This is a re-affirmation of what I’ve been saying all along about this awesome device! The PRX150-Pro simply retains the tone you work hard for – no matter how much attenuate your signal; and more importantly eliminating the need to compensate with EQ.

Check out Aracom’s Gene Baker audio page here!

Having someone like Gene Baker demonstrate the capabilities of the PRX150-Pro is huge! Gene is an incredible guitarist!

goldie41I spoke about Tone with a capital “T” the other day and how your Tone is the combination of your gear plus what’s in your heart. One thing that I didn’t discuss is that when your heart and your gear are in alignment, the visceral effect it has on you borders on a religious experience. Put simply, you become truly inspired. I got Goldie back from Saint Guitars a few days ago to correct some wiring and action issues, and plugging her into my amp, I was immediately floored by her tone. I already was in the first place, but with everything working right, the effect it had on my spirit was tremendous!

So I decided to completely re-write and re-track a song that I had recorded earlier as a demo of the Reason Bambino – turn it into a real composition. But I also wanted to demonstrate the wonderful voice she has. Here’s the song. It’s called “Sunset By the Bay” because it reminded me of sipping a mojito on the beach at sunset:

The opening of the song and the first “verse” demonstrate Goldie’s neck pickup in single-coil configuration. Man, it’s chimey like a Strat! The second part of the song stays in the neck pickup but with both coils working, and adding a bit of crunch in the second channel of my Aracom VRX22. I recently had a mod done to the amp to add channel switching, and remove the Master Volume control from the first channel so it acts more like a Class A amp in channel 1. Continuing on, in the bridge of the song, I switch both pickups and remain in channel 2, then I finally finish up back on the neck pickup.

I can’t believe the sounds that come from this guitar, and my VRX22 just sounds so sweet with it!

By the way, as far as the recording of the melody goes, I recorded Goldie completely dry, just plugged right into my amp. I then added some reverb and a tiny bit of delay to give the melody an airy feel. The rhythm part was recorded using my Strat directly plugged into my Reason Bambino and played entirely in the Bambino’s Normal Channel. I love the natural presence of the Bambino – it was if it was made for a Strat!

I also recorded the entire song at bedroom level using my Aracom PRX150-Pro attenuator. I just love the purity of my tone at any volume level!

I’ve often extolled the virtues of a cranked amp here at GuitarGear.org and elsewhere. My belief is that when you’ve got both your pre-amp and power tubes working, you get the real character out of your amp. There’s something that happens to your tone once you get juice into your power tubes that adds a certain dynamicism and complexity that you just can’t get with just your pre-amp tubes. Unfortunately, most mere mortals, like myself, don’t normally play venues that that will allow us to crank our amps to the point where the power tubes of our amp come into play.

Take, for instance, my good buddy Phil. He’s the lead singer of a bar band called Phil ‘N The Blanks. Up until recently he was playing through a Marshall DSL100 JCM2000 100 Watt head into a Marshall 1936 2 X 12 cab. Talk about too much amp for his gigs! I ran sound for him at a gig a couple of months ago, and could only turn his volume and gain controls to about 3 each before he stepped on the band entirely; not to mention peeling faces off! Since he’d owned the DSL100, he’d never played above 5 because it was way too loud.

Recently, I lent him my Aracom PRX150-Pro attenuator so he could squelched down the volume but crank up his amp. He couldn’t believe his ears! He was finally able to get the gain up in his amp where his power tubes would break up. It was like a completely different amp once he heard the cranked up tone. I had been telling him for months that there’s really nothing quite like a cranked up amp, and for the first time since he owned the amp he was able to hear for himself what I had been talking about. Before that, he was on tonal training wheels! 🙂

Ultimately, he decided against going with an attenuator, but he did a very smart thing: He purchased a low-wattage amp, the Marshall Haze MHZ15 15 Watt amp. It hasn’t arrived yet, but I’m excited for him because he’ll be able to crank that amp at a reasonable volume level, as the lower wattage amp will break up a lot earlier, and he’ll be able to reap the benefits of the response of his cranked amp!

1 Watt is LOUD!

But here’s the funny thing: 15 Watts can still be freakin’ loud when cranked! The following chart shows SPL at 1 meter vs. Wattage (I got this from the Aracom site where Jeff discusses understanding attenuation).

What’s amazing from the table is how loud 1 Watt is at 1 meter! It’s as loud as a jack hammer! And 0.0312 Watt is as loud a vacuum cleaner! Jeff got this information from a well-known study done in 1933 by Harvey Fletcher and W A Munson about human hearing response. For those people who say, “P-shah” to low wattage amps, just reference this chart.

Granted, there is a certain mojo about a 100 Watt amp cranked up – even a 50 Watt amp. But most people other than those playing large venues can crank their amps to experience that mojo. But in spite of that, there’s been a movement in the industry these past few years towards lower wattage amps. I think a big part of the reason for this is the improvement in PA gear over the years. Want to get your sound out there? Mic your amp. After all, all you need is stage volume so you can hear yourself. Let the sound guys project your sound out.

My buddy Vinni Smith of V-Picks does exactly that. As amazing as he is with a guitar, he gigs with a Roland Cube 30! He just gets his stage volume, then has his amp miked to get his guitar out to the audience. This dude gigs alot, and he’s living proof that you don’t need a lot of power to get perform. As long as you can get your tone, you’re golden!

Circling back to the title of this article, there really isn’t anything like the sound and feeling of a cranked amp. Especially with tube amps, when the power tubes have juice, they add all sorts of things to your tone such as compression, a different kind of breakup and even more touch sensitivity. You can get that in a couple of ways:

  1. Get an attenuator. There are several on the market, including the increasingly popular Faustine Phantom, but my bet is on the Aracom PRX150-Pro, as it takes a completely different approach to attenuation than all others. I’ve never played an attenuator as transparent is this.
  2. Get a lower wattage amp. I’m not even going to list what amps to buy as there are tons of fantastic amps – both boutique and mainstream – on the market. Just make sure you give them a listen.
