Hi I may sound stupid but I just don't know that much about gear prices so i was looking for some advice. Is 900$ a good price for an Ampeg SVT Classic head (year 2003, made in the USA)? I'm most likely checking it out tommorrow. I think if i pick that up then i can get a hopefully used 4 by 10 ampeg cab. Thanks for the advice. The head appears to be in good shape judging by the pics. Anything imparticular I should look for while checking out this amp.
