|Aracom DRX Power Attenuator
Summary: Truly an evolution of the attenuator, Jeff Aragaki has once again upped the ante with the DRX attenuator. This dual-level attenuator not only will tame your volume, but it will give you the ability to use two different volume levels; and with the optional foot switches, will give you flexibility not offered by any other attenuator on the market. Furthermore, the adjustable reactance allows you to tame your tone on top of controlling your volume.
Pros: The Aracom attenuation technology is the most transparent that I’ve tested – and I’ve tested and used several over the years. Nothing comes close. But the dual-level attenuation (normal and boost modes) blows away the competition in my book. Then add variable reactance to the mix, and there’s nothing that can even touch what this attenuator can do.
Cons: Is a little on the pricey side, but the capabilities are worth it to me. I’m having one built.
Price: Starts at $850.00 direct
Tone Bone Rating: 5.00 ~ A few years ago, when Jeff first showed me his prototype attenuator mounted on a pine board, I never thought that
Jeff Aragaki is a genius. I knew it from the first moment I met him. I started out by first being blown away by his “more Marshall than Marshall” amps and now the proud owner of three of them to witnessing his attenuator technology go from a project box, demonstrating to me a way to throttle output volume that was unlike anything at the time (and still no one has been able to duplicate what he has done), to now three iterations of attenuators (Pro, DAG, and now the DRX). The DRX is by far his most incredible riff on his unique attenuation technology. And no, if you think you know how it works, you’d be wrong. I’m no expert, but I’m familiar with the basics of traditional attenuation (read: everyone else’s attenuators), and the Aracom technology is like nothing on the market.
As I mentioned above, the DRX (short for DualRox) attenuator takes that technology to a new level by offering two modes of operation: Normal and Boost; at least if you’re just using boost mode (Type A foot switch). It opens up more possibilities with the Type B and Type C foot switches which provide the capability to switch channels (Type B), or use an A/B (Type C), perfect for two-channel amps that don’t have channel switching. These features alone had me completely sold on the unit, and I had only originally tested it with the Type A foot switch! My test unit which Jeff lent to me for review included the Type B boost and channel switch (which I’ll demonstrate in a clip below). But irrespective of the type of switching, being able to boost my volume under attenuation just blew me away!!! Here’s a clip that demonstrates only switching between normal and boost modes:
From a performance standpoint however, having both the dual attenuation levels, plus the ability to switch channels is absolutely HUGE! For instance, I can go from clean to full-on overdrive with the click of the foot switch; much like engaging an overdrive pedal. But there’s no pedal involved. Without an attenuator, going from clean to dirty on the amp usually involves a huge jump in volume. But with the dual-level attenuation, I can set my cranked up volume to just a bit over the clean volume. Again, this is just having an overdrive pedal, but this time, it’s only my amp, so I don’t have to worry about dialing in another device’s EQ to get the right tone. Check this clip out:
I used my Aracom VRX22 for that, which is another Plexi clone but with 6V6 tubes. This amp is notable for its haunting clean tone, and monster overdrive, which comes from 1950’s NOS 6V6’s that I have biased a little hot. I also had it customized with channel switching, so it fit the bill for testing out the Type B foot switch. I just can’t wait to gig with this come Sunday! It’s gonna be fun!
But it doesn’t stop there. In addition to the dual modes is a feature that no one else has, and that’s the Variable Dynamic Control. While it acts essentially as a subtle high-cut filter, it’s not an EQ. Instead, it changes the reactance between the attenuator and speaker. Fully right is full reactance, and as you move left to the leftmost position (there are 5 positions), the reactance is reduced, producing the effect of rolling off the highs. But it’s very subtle, and you can really only tell a difference between the most extreme settings. This is an incredible feature in that it allows you to dial in your tone; especially your cranked tone. For instance, my Aracom VRX18 (18-watt Plexi clone) produces lots of highs when cranked. They’re not entirely undesirable, but they do get piercing, especially at gig levels. So by slightly reducing the reactance between the attenuator and speaker, I can get rid of the super-super highs while retaining my fundamental tone. In a word: Killer. Here’s a clip that demonstrates the Variable Dynamic Control:
As I said, it’s subtle. The fundamental tone doesn’t change much, but going from extreme to extreme, you can tell when the highs roll off a bit.
For those who are familiar with the previous Aracom attenuators, one feature that set them apart was the ability to mix and match amps and cabs with different impedance settings. For instance, you could match an 8 ohm amp output with a 4 ohm cab. But that came at the price of a huge transformer that made those units weight 18 lbs. The DRX requires that both amp and cab impedance settings match. But that’s not really a loss at least for me because all my amplifiers have multiple output impedance jacks, so it’s really not a big deal. And for what I get in return from the DRX, that loss of flexibility is not a very high price to pay.
When I first tested the prototype of this unit a couple of years ago, I actually thought that Jeff had changed the circuit technology. But in fact, he didn’t, which is a good thing because when you have this unit, you’re assured of getting the most advanced attenuation technology on the planet. Yeah, I’m raving about it because for the past few years, this technology has afforded me the flexibility to play in ANY venue, large and small, indoor or outdoor, and not ever have to sacrifice my tone; something I can’t say of other attenuators I’ve used and tested. I can crank up my amp as much as I need, confident that my tone hasn’t changed, but never having to worry about pissing someone off about my volume.
But on top of that, with the ability to have two levels of attenuation, plus the ability to dial in my highs, I couldn’t be happier, and I can hardly wait for Jeff to finish constructing my unit.
And yeah, as I mentioned above, it’s a bit on the pricey side. But how much is great tone worth? I’ve spent countless hours and thousands upon thousands of dollars on guitars, amps and pedals over the years – especially the last few years – and with each one, I justified my expense. The DRX is a tool that will let me ensure that I keep the tone that I’ve worked so hard to achieve. It may not make sense for the solo bedroom player, but for working musicians like myself, the DRX is an investment in my tone that I’m willing to make.
