I have a VOX AC30 I'm trying to sell, and a guy wants to trade me a 70's bassman head for it. I tell him I can't do that straight across, so he tells me he has another amp and speaker cab (non-Fender), and sends me a few pics. I know what the Traynor is suppose to be, but this one has a switch for On/Standby . I can't find another like it on the webz. Anyone have any experience with 'em? He hasn't answered me back yet or of course I would know. That was my first thing to do.
