V4s are super rad. Look around for one and don't forget to play with the switches. They change what frequency the EQ knobs are set to. Also, the V4B is the "bass version". The only difference being that it doesn't have reverb.
Earlier Sound City amps had a designer from Hiwatt on the team and are very similar amps because of it. I'm sure you can find more specific info if you look around. I've never played one myself.
