Revv G20 settings
Channel 1 is the clean channel and Channel 2 the high-gain one. The Gain knob and the three-way Aggression switch work on Channel 2 only; Treble, Mid, Bass, Volume and the Wide switch are shared. Wide gives Channel 1 more push, brighter highs and fuller lows, and extends the low end of Channel 2.
⚡ Match a tone on this ampHow do you dial in a specific tone on a Revv G20?
A valve amp does not respond to a knob the way a number on a page suggests. Where the Revv G20 sits in its own gain range changes what every other control does: the same treble setting is bright at low volume and harsh once the power section is working. That is why copying an artist's numbers onto this amp gives the wrong answer, and why the settings here are written against this amp's behaviour rather than the one the record was cut on.
Name the song you are chasing and Tonelify returns the settings for this exact guitar amp, not the settings the original artist used. Those are two different things: the recording was made on gear most players do not own.
Settings for this amp only ever use controls it actually has, because its front panel is stored in our gear database. You will not be told to set a knob that is not on the amp.

What the Revv G20 panel means when you dial it in
20W, switchable to 4W. At that rating the power section starts working early, so the loudness knob is part of the tone setting rather than separate from it. There is no presence control on this panel, so everything above the treble band has to come from the treble control and the guitar's own tone knob. A setting copied from an amp with presence has to be rebalanced here. Drive and volume have separate knobs, so the amp can sound driven at a volume that is liveable. Where a tone sits between the two is part of the answer, not a detail. 2 channels, Channel 1 and Channel 2, and a setting only means something once the channel it belongs to is named. The selectable voicings are Aggression off, Aggression Blue and Aggression Red. Picking the voicing comes before the knob positions, because the same numbers land somewhere else on each one.

Revv G20 questions
What are good starting settings on a Revv G20?
Start from the middle of the range on Channel 2 Gain, Treble, Mid, Bass and move one control at a time. There is no single correct set of numbers for this amp, because the target changes with the song. Tonelify writes the values for a named tone against this amp's actual panel: Channel 2 Gain, Treble, Mid, Bass, Volume, Wide switch.
Can the Revv G20 get a metal tone?
It depends on how much gain the amp makes on its own. Where a valve amp runs short of gain, a drive pedal in front of the input adds saturation and tightens the low end at the same time, which is how most of the amp's own range gets extended. Tonelify says which of the two routes a given tone needs on this amp.
Does Tonelify support the Revv G20?
Yes, and its front panel is stored, so settings only ever reference controls this guitar amp has: Channel 2 Gain, Treble, Mid, Bass, Volume, Wide switch. You will not be told to set a knob that is not there.
