Thanks guys. I've just spoken to the owner. Even though he's used the rig on tour, he doesn't know much about it. The head power's up, but no volume. The cab is exactly like he bought it. He looked at the speaker jack plate on the rear and it has 215B, 400 watts and 4 ohms with 2 jacks. He also said something about a metal plate was missing from the front. Was there a 215 B with that kind of power? Is there a picture of what a stock one should look like somewhere? I found several on Google, but I'm not sure which one this is or should be. I'm going to look at it tomorrow, but it's the only shot I'll have at making a decision on it due to circumstances. If it's just way, way butchered from what it's supposed to be, I'm guessing finding the correct stuff might be difficult??? Anyway, any advice is appreciated. BTW, the Jazz bass is a 2006.
