firstly play some music through (e.g. plug your phone in) it for half a dozen hours or more with cushion or something in front of the speaker (to bed the speaker in)
get the amp up off the floor (the tone changes dramatically depending on height and placement in a room)
is it open back? if so you need to have play with the distance from a wall or just completely open.
typically, the best tones can be found via
adjusting each dial to point where it dips in an out (the sweet spot) sonically (on tone dials & gain dial) - that'll give you a basic clean to break up to be adjusted by your guitar volume/tone dials
make note of your settings then tweak from there, to each type of tone you want
again take notes
of the best settings.
that's my method, but I could be completely wrong.
