Yeah , of course , I don't know the beast but I had a boogie once and it's really a sensitive gear and one knob can interact ( non linear ) with other settings, so it's really tricky.
here is the PDF docs : (lots of settings on page 11 , very usefull docs indeed , 5 pages just to explain the EQ settings !!! )

I'm interested in :
(5) Jazz Rhythm 1, Warm, Round, Clean Rhythm 2, Soft Clipping Lead 1, various functions and how they
interact.
