Revv G20 Amp Head Reviews

Ticks all the boxes and more...

After playing live for over 30 years, lugging 100watt+ tube amps and their respective speaker cabinets, my physical body started a "less weight more play" campaign.

A variety of options are readily available in form of modeling amps, toneprints, profiling amps,... All lightweight, with endless options of mimicking sounds.

Then I bumped on a youtube video about "lunchbox amps" and as I own a superb Orange OR100, (needs a forklift to move) the options of a lightweight, smaller version looked immensely practical.

And then the Revv G20 came up... Having known REVV for their "purple channel" on their 120 watt flagship amp, my interest was peaked.

And the G20 dellivers, the clean channel is not useless, but you do need to "tame" the output of your guitar in case of high output pickups, as it will break up very easily.

The gain section was apparently taken from the generator series and offers 3 switchable gain stages, however subtle these may seem, there is a very noticeable difference.

In combination with the built in two notes torpedo impulse module, the versatility becomes near infinite.

As sound, in my case high gain, is mostly dependent on the speakers used.

Another perk when shifting through the impulses, was that my goto speaker cabinet (H&K GC412 Triamp cap greenback) was readily available as a preset.

All this is programmable by midi, and setting this up is a breeze.

Hooking up aforementioned greenback cab, this amp is LOUD!!

But when heavily driven, it's also pretty noisy, and one needs a pretty good noise gate to keep this down.

The gain stages vary from a typical rocky crunch to full out "these go to 11" high gain.

Rotary knobs are however not midi programmable, so going from summer of 69 break up, to Handshake with Hell full gain will require a slight turning of the gain knob... :-)

And it handles B tuned guitars as a dream, no definition loss, and as Ola once stated, IT CHUGS.

As this is a full tube amp, it's responsiveness to picking strength or guitar volume rolloff still beats any profiler imo, while in combination with an FX module offers the same versatility.

And more recently I've been using the G20 for this goofy rock coverband, using a HD500 in the loop, and it's getting nothing but compliments on the sound it produces.

And then there's the studio applications...

Doesn't need a load, just straight into the DAW, and bob's yer uncle.

Revv really hit the mark with this, full tube, ease of use, incredibly versatile in sound, programmable, full tube, torpedo two notes, full tube...

Awesome lunchbox amp

Pros:

-Sound quality is amazing

-Easy to handle

-two notes IR

-Midi in

-protective circuit to use with no cab

Cons:

-output level knob should be bigger and with locking mechanism.

- there is no between clean and hi gain channel

Ok, but not great.

The clean channel is overdriven and more like a crunch channel. It does not have a gain control. The gain control does nothing when the clean channel is selected. This makes the clean channel completely useless.

The overdriven channels give a modern tone but are far far away from what I'd call "high" gain. And the american "scooped" death metal tone is not possible to achieve with the EQ that it is equipped with.

However, with a distortion pedal in the FX loop of the clean channel I'm happy. But that makes the tubes a bit obsolete....

The build quality is very solid and the features are great for recording in a home studio.

Perfect High Gain Amp

I use this amp for couple of weeks as main practice amp with headphones. Sound is very good, clean sound is just amazing. Gain channel provide wide range of gain. Mainly i play modern metal and it's fit perfectly for this. Cabsim also provide several nice presets and I don't have any problems with this feature.

Definitely i recommend this amplifier
