Revv Owner’s Manual - 10
The amplifier has a midrange focus & to modify this you can either slightly
dial back the mid control or switch between the two Contour options for
a bright upper-mid focused sound (on) or a thick lower-mid focused
sound (off).
Bright & Fat extend the highs & lows respectively. I find it is best to
engage these if you prefer the overall tone either or both provide & then
set the treble & bass knobs to taste, accounting for the voicing switch
positions. Fat is also a useful tool when switching to a single-coil
equipped guitar.
As with Channel One, Channel Two has an independent 100 watt / 10
watt Output Power Switch. 10w mode will help achieve satisfying sounds
at lower volume and/or give you the option of a tone featuring more
power amp saturation. All else being equal this will result in a more broken
up oldschool sound, compared against letting the preamp take care of
much of the gain in the higher headroom 100w mode.
