The GAS is strong with this one. There's what seems to be a really good deal here locally on a mid-70's Ampeg V-4B, recently serviced and fully re-tubed with documentation thereof. I don't need another amp, but the only all-tube amp I have now is my Fender 400PS and I've never owned any Ampeg gear to speak of, which sounds a true travesty having been a bassist since 1980 or so... So Ampeg fans, please tell me the good, the bad, and the ugly about the V-4B. Are its conservative 100 watts really enough to drive a non-hornloaded 2x15" cab sufficiently in a classic rock/blues bar-band without running through the PA? Fill me in, please.
