The Tonelab manual has more information than the AD30VT manual; go find that at the VOX home page and read it.
You should really explore the tone space not just mess with gain etc to find the sound you're after. This was a revelation to me. I get better sounds the more time I spend with a particular model.
As Nelskie has often remarked about modellers, it takes a little time to understand them.
