isn't there like 3 knobs on the whole thing. My most unhelpful post ever but its not exactly a Mesa MKIV when it comes to tweakage.
You should ask about speaker combos, OD boosts etc.
I have the 2204 4010 combo
I use the low gain input on mine for a excellent clean tone.
Pre volume about 2-3 o'clock, master around 10-12 o'clock
treble 9-10 o'clock, mid 11-12 o'clock bass 2 o'clock presence 11 o'clock
something like that. Great barking clean tone with serious punch.
not me? I didn't post a clip, sorry.
