That is remarkable news about California. I guess Bob Heil is way ahead of the curve on this one (and RG, too).
As for the V-Amp, I had trouble with presets on mine (V-Amp 2), and replacing the little lithium-ion fixed it (although not without the joy of having to repair the crappy battery holder with superglue when a itty-bitty plastic clamp broke off). Doesn't sound like your problem, though. Can't hurt to try, but be careful with that battery holder--don't try to force anything. Good luck.
