Hi There, I'm new here also because I'm trying to find some answers regarding an old '70s bass rig I got. It's an Ampeg SVT, the real thing. It's big, heavy and awesome. The straight back 8x10" is a real back breaker, and is attached to the original dolly. My P bass sounds great on it, just like my fake but okay strat. I got it for 15 years or so, but since i switched to drums haven't used it much for the last 9 years. Friends used it however. So on the front it looks like other early/mid seventies SVT's I've seen. white frequency switches, the lines aroung the knobs are rounded. My question is printed on the back. It says model SVT V9. So there's people telling me it's a guitar head. Like the Stones used, and Steve Morse uses. Allright, there's many amps without preamp knobs. But all I can find about these V9's is that they are real guitar amps with reverb. Mine doesn't have any reverb. Just two channels. The amp sounds different from one a mate of mine owns. It's got a real thick lo-end. Mine's in a better shape, that's for sure. It's way less distorted than my friend's. It's pretty clean. If anyone can set some light on that V9 printed on the back, that would be great. As a guitar amp it's real damn loud, louder than anything I know. I gotta turn it up quite a bit to get a good tone; the sound is earth shattering but totally awesome. The van makes a massive noise. Guess I look for a replacement working on 110 volts. The 230 volt action I had done, I live in the Netherlands, happens at some point closer to the transformer. Can't find those in Europe. And there's a considerable real low hum. That wasn't fixed in the fixing action. I also tried to find info on what it's worth, which isn't easy but of no real interest right now. I can swap it for a Sunn 1200S from '68, but am afraid I'd regret it later on. I wonder what it will sound on with one or two cool 4x12" cabs when I wanna blast guitar through it... A long first post. But I'm a man with a sound huger than anything I know, and some burning questions on the side.
