Made a thread asking some questions about this amp not too long and want to thank all of those that responded for their help. It almost convinced me to pass on the amp, but I decided I should at least go talk to the guy, play it, and make an offer if I wanted it. The story is the guy bought it in 1981 as part of a package deal. He was buying an old cream Les Paul Custom and the seller offered to throw in the amp for an extra $50. At some point he had a 3-prong added. It mostly sat unplayed since it didn't really match his preference for heavy rock/metal tones. Best guess is that it's a 1966 based on tube layout. It was listed for $400, which seemed like a reasonable price to me. Reverb sales go from about that range up to the $700's. I did get a chance to check it out as thoroughly as possible without taking it apart and got to play it. Probably a healthy dose of mojo dust clouding my brain here, but it sounded freaking great. Trem was nice. Reverb was lush and wonderful. Full sounding tone that really pulled my strings. So, getting to the point - I really wanted. Explained to the guy that I loved it, but also that it was at best a player grade amp and I was going to have to invest a few hundred into it to get it into giggable condition. Offered him $300 for it, along with the opportunity to wait and see if he could get a better price from someone else. Apparently he hasn't even got another inquiry in the few weeks it was for sale. He said that he felt it should be played and if I was planning on gigging it he'd sell it for that price. So, I feel like I got a great deal! Placing some calls today to check on a cap job. Going to try to find someone with Ampeg experience. I'd love to do it myself and feel like I'd have the ability to do it with a little help, but nobody around here to show me. I need to get a toothbrush and some goo-gone to see if I can clean it up a bit. I've heard the diamond covering is a pain to clean. Fliptops.com has a period correct handle that I'll be picking up. Likely will replace the speaker with a C Rex I have to avoid damaging the one that's in there. No clue if it's original. I may explore replacing the tolex, but no hurry there. Again, thanks everyone that helped with my research. This is my first vintage anything and I'm pretty excited. Some pics!
