I'd advise against it totally- even with the amp off there's potentially :o :o :o LETHAL VOLTAGES INSIDE  :o :o :o - far better to adjust the OD trimmer with the amp turned off & isolated from the mains supply & then flip it over on top of insulating material of some kind so there's no danger of a short- and then try it through speakers.  I found around 10 o'clock on the OD trim was plenty for Robben Ford type sustain- the other trimmers I would advise against moving- they're for tube balance etc...

hope this helps.  ;D

No problem with the actual turning the FET and OD trimmers, its what you might also touch thats the problem. I've got mine on the rear panel and it has taken a while to find the right settings, and they vary depending on the pickups. The FET trimmer I've not really messed with since I haven't really found a use for that input yet, apparently a piezo pickup works well thro'  it.

ah thanks, touching things wont be a problem, it can easily be adjusted by applyinga small force from the top using a chop stick.

What if you hypotheticly wired the overdrive trimmer pot to and expression pedal so you could adjust it while you play? Would that be safe for the amp? Just curious.
