I might be doing a trade deal for a 2000 model VAC 22 watter in 1x12 combo form. I haven't been able to find a manual to describe normal operation, so if any of you guys can tell me all about your experiences with them and how you setup the amp, I would be most appreciative. In searching through the threads here I've found that I will probably send the amp back to Rob P. to have it updated to the final revision. The amp in question was updated in 2002 by Rob, doesnt have a mid knob or VAC logo either, but does have reverb and an FX loop. Thanks a lot.
