Revv G20 Amp Head

Geweldige versterker voor de (home) studio en met genoeg volume om in een band te gebruiken. Clean en gain-geluiden zijn geweldig. Dit is geen one-trick pony, wat mij betreft, maar juist een zeer veelzijdig ding. Wel een multi-effect of een paar mooie pedalen toevoegen, in ieder geval reverb en delay. Eén klein minpuntje. De instellingen waarmee de versterker start zijn te programmeren maar dat kan maar voor één van beide kanalen. Het andere moet je handmatig doen (wide, 4 watt, agression-mode). Maar dat is een kwestie van een paar knopjes indrukken.
Toen ik de versterker bestelde kreeg ik een exemplaar zonder knoppen toegestuurd. Contact opgenomen met Thomann en de versterker teruggestuurd. Van Thomann ontving ik heel snel een ander exemplaar, met knoppen. Prima service, Thomann.

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.

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...

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.
