This is a home guitarist dream!
crash2032, 12.05.2020
Seems like I am the first one user here, at Thomann :)

During the whole of my music career, I played mostly with modular processors, like Line 6 HD500X. I'd say, that it's pretty decent and easy to use stuff, especially when you are touring guy. But when we speaking about recording - using floor processors is not a great idea. Some high end digital harsh, lacking natural response made me start to look for something new, some gear, which helps me within my home studio and during touring as well. And now Revv G20 story begins. My main requirement was to have small watt amp, small size device, with crystal "clean" sound and aggressive "overdrive", for covering all my basic needs. What I like about Revv G20, that it includes everything and more. "Aggression" switch really change rules, and makes the sound very different, which is very useful, if you have some differences between lead sound and rhythm sound. Additionally, embedded Torpedo Load(probably captor X) helps you to be in peace with your neighbors and easily practice at home. Probably the main cons are that you have to look for some complex midi-switch to control this beast.

Ok, but not great.
Fungophago, 23.07.2021
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
Brivang, 02.02.2021
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

Nicht so gut, wie alle sagen
chr1stoph, 21.11.2020
Um es gleich zu sagen: Wer ausschließlich Metal spielt und genau den Sound dieses Teils mag, wird ihm komplett 5 Sterne geben. Aber ich wollte wissen, ob man den G20 auch flexibler einsetzen kann, und da ist die Antwort nein bzw. nur mit größerem Aufwand.

Der G20 ist ein One Trick Pony: stark mittenbetonter Modern Metal, das kann er. Aber der Clean-Channel lässt sich nicht mal in einen leichten Overdrive treiben - er dient wirklich nur als Basis für Effektgeräte, das heißt, da braucht man weiteres Gerät. Der G20 kommt ohne Reverb, und der "Wide"-Button macht exakt gar nichts. Das heißt, auch da braucht man noch weitere Hardware, um mehr draus zu machen. Die Flexibilität der Klangregelung generell, auch im Gain-Channel, würde ich als niedrig bezeichnen, trotz der verschiedenen Aggressivitäts-Voicings. Denn selbst mit maximal aufgedrehten Höhen kriegt man nur ein zwar differenziertes und knurriges, aber dumpfes Mitten-Brett ohne Brillanz aus dem Revv; wer seinen Ton auch nur annähernd in der Marshall-Ecke verortet, muss hier gar nicht erst suchen.

Auch das lässt sich bestimmt mit vor- oder nachgeschaltetem EQ verbessern. Aber man muss klar sagen, dass der Revv kein Standalone-Teil ist, sondern eine Art Klangzentrale, die in der Mitte einer ganzen Menge weiterer Hardware stehen sollte, und zwar im Studio- oder Homerecording-Kontext. Dafür ist er dank der wirklich tollen, für alles und jedes verwendbaren Ausgänge - die Cab Sims! - hervorragend geeignet. Aber ich kann mir nicht vorstellen, damit on the road zu gehen, denn das Versprechen der Unkompliziertheit eines Lunchbox-Amps wird m.E. nicht eingehalten, wenn man ihn erstmal durch mindestens ein halbes Dutzend Tretminen tauglich machen muss. Es sei denn, wie gesagt, man spielt skandinavischen Power Metal.
