On Low Wattage Amps

I love low wattage amps – those that are 10 Watts or less. I have a few. For years, people eschewed these super low wattage amps, and passed them off as mere practice tools. But I suspect they really didn’t understand what a super low wattage amp brings to the party. Low wattage amps such as the 5 Watt Fender Champ helped define the sound of rock and roll. Listen to classic rock tunes, and more likely than not, the venerable Fender Champ would be the amp providing the sound.

Today, more and more people are turning to low wattage amps – especially home recording enthusiasts, and even pros like Jeff Beck – to save their ears and to get crunch and grind at low volume levels. As a result of the increased demand, many manufacturers, boutique and mainstream alike, have responded and come up with a slew of low wattage amps. It’s a good thing and a bad thing. On the one hand, you have tons of selections, on the other hand; well, you have tons of selections. There are a lot of them out there and it’s tough to decide which way to go.

The shear amount of low wattage amps on the market is perhaps a big reason why Marshall waited so long to come out with its super own low wattage amp. Perhaps they were studying what the market responded to and what they could do to address what people might have fed back as improvements that could be made.

Enter the Marshall Class 5 amp. This amp was released in the UK near the middle of last year, and arrived here on our fair shores around November of last year. Amazingly enough, news about this amp has been relatively quiet. There hasn’t been all that much advertising that I’ve seen about this amp. The Marshall Haze amps have gotten lots of “rag” time, and the response to those amps has been generally positive. But I haven’t heard much about this amp other than user reviews. That’s too bad because after playing it, I have to say that I really dig it!

Classic, Killer Tone!

Is Marshall embarrassed about advertising such a low wattage amp? I certainly hope not, because I got a chance to play this amp today, and I just have two words to describe it: KICK ASS! Built upon the “Bluesbreaker”/Plexi pedigree, the Class 5 has all of that Plexi goodness in a low wattage combo. Make no mistake: The Class 5 packs a serious punch; maybe not maximum volume-wise (for a gig, this amp would need to be miked, but will provide plenty of stage volume), but if you’re looking for those classic Plexi tones in a low wattage solution, look no further!

Because I was in a shop, I only tested it with a single guitar: An Epiphone Les Paul Ultra. But the Class 5 delivered that cranked Les Paul through a cranked Marshall Plexi true to form. It was everything I expected to hear from a cranked Plexi, just at a lower volume. That really blew me away!

There’s really something special about that tone. My Aracom PLX18BB is a super-close replica of the Plexi 18, plus my good buddy has several Marshalls including an original JTM45 and Plexi 50, so I’m very familiar with that classic tone. While the Class 5 is just a tad grittier in its overdrive than its more powerful siblings (perhaps due to the new speaker), the rich harmonics and smooth overdrive delivered with “balls” with a gorgeous sustain is all there.

While it might seem from my description that this amp isn’t very loud, it’s plenty loud. You can even gig with it easily, even with the stock 10″ speaker which, by the way, has tons of volume and provides rich tone. I was actually expecting the amp to sound a bit thin due to the smaller speaker, but there was nothing thin-sounding about the amp.

Another reviewer mentioned turning the bass all the way down, because he thought it was flabby. I really didn’t detect a flabbiness to the bass, but I like a bright amp anyway so I had the bass EQ dialed down to about 8pm which is almost off.

All this tonal goodness is delivered by a 10″ speaker specially developed for the Class 5 by Celestion, the G10F-15. As expected, the 10″ really has an emphasis on the mid- to high-frequencies, but Marshall compensated for the lows by providing a spacious cabinet to act as a nice resonance chamber for the speaker. The result is a very balanced and smooth tone, if a little on the bright side. But bright is what Plexi’s are all about, and the Class 5 delivers on that swimmingly!

As far as my customary test clips go, sorry, this was a shop eval, so I didn’t record any. But if and when I get the amp, I’ll post some for sure!

Yikes! It’s Too Loud!

Hello… 5 Watts is loud. In fact the speaker’s SPL is rated at 97dB at 1 meter with a power rating of 15 Watts. People have complained that they can’t crank it up in the bedroom past 3 or 4. Yeah… welcome to the Non-Master-Volume club. But that’s the beauty of the Plexi in the first place! You need to saturate the power tubes as well as the preamp tubes to get that Plexi vibe. If you need to run this amp at bedroom levels, the best solution is to get an attenuator such as the Aracom PRX150-Pro.

I sincerely hope that Marshall doesn’t cave in to those complaining it’s too loud and add a master volume to the amp. To me, it doesn’t need and would take away from its vibe.

Made in the UK

This amp is constructed in the UK, amazingly enough. And what’s even more amazing is that it sells for less than $400! The shop I tested it at had it a retail price of $389! One would expect those kinds of prices to come from gear manufactured in Asia. But not this beauty. So to have a UK-made amp at this price point is truly remarkable! Then to get tone this good? OMG! Truly amazing!!!

Fit and Finish

This amp is extremely well made. The cabinet feels real solid, and nothing was loose. Apparently, earlier versions suffered from a buzz, but the unit I tested didn’t have that at all. In any case, I inspected the amp thoroughly – front and back-  and didn’t detect any finish flaws. The tolex was nicely molded down to the surface of the underlying wood, and there were no loose pieces of material. From what I could tell, 1/2″ ply was used for the cabinet, and that is good because I’ve found, at least from a purely qualitative perspective, that cabs built with 1/2″ thickness tend to resonate quite well. This obviously helps bolster the bottom end, and it does it nicely.

The rear of the cab is interesting in that it is partially closed with about a 4″ opening, covered by a metal grill. I suppose that this is so you don’t throw in the cable and accidentally puncture the speaker cone, but it may be purely aesthetic in nature. The rear grill is rather cool.

Overall Impression

I totally DIG this amp! It was fun cranking it up in the store this afternoon! Admittedly, the amp doesn’t really hit its sweet spot until the volume knob is about midway. But completely cranked up, it produces the tone I expect out of a Plexi! And even cranked up, it responds well to volume knob levels, so you can clean up the amp quite easily.

Compared to other super low wattage amps I’ve played, even my venerable ’58 Champ, this amp has tons of balls in stock configuration. With my Champ, I had to have an amp tech add a 1/4″ jack so I could run it into an external cab because the 8″ speaker really can be quite thin-sounding. But the Class 5 has enough balls and volume stock to not need any of that (though it’ll be fun to run this into an external cab anyway, which I plan to do).

Note that unlike other reviews, I really didn’t make mention of the amp being “Class A.” That’s a big deal with lots of folks, but to me, even though I understand the classification, it really doesn’t matter. What does matter to me is how the amp sounds, and it simply sounds killer. In my book, I couldn’t care less about an amp’s classification so long as I can get great tones out of it; and the Class 5 will certainly deliver on that!

As you might surmise, I’ll probably end up getting this amp. As if I need another! But it’s a great amp at a great price. That’s just plain tough to ignore! And note that this amp sounds so good stock to me that I really don’t see a need to swap out tubes unless they burn out (which they probably will considering I’ll be running the amp all out all the time 🙂 ).

Here are some cool video clips of the Class 5 in action:
