OK, I may have found my amp, and also may have found another singer/guitarist for Ann Arbour. Exciting stuff! The amp is a 1980 JMP, which is master volume and is also 100 watts, which isn't exactly what I wanted, but that's OK. The guy lives in Key Largo, and it's a good deal. He doesn't email back very quickly though, and I'm hoping I don't lose the deal to Ebay or something. We're also talking to a guy who is in another local band who is looking for a chrisitan band to join and seems excited about helping us out. He's got a great voice and has some good equipment, so rock!
