Hey guys, At my local music store, there is a 70's (73 I believe)Twin Reverb for sale. I can get it for 925. It is in pretty good condition, for it's age. It definitely looks like it's been well loved... The speakers are not original. The amp sounds terrific and everything seems to be in good working condition, which I cannot say for the other twin, a '74. The reverb is busted on that guy. Fender with no reverb is like a cobra with no venom. What do you get? A belt... Anyhow, Is this a fair price? In general, what kind of maintenance and tune ups do these amps usually require? All in all, is this an amp to jump on, or is it nothing to write home about? I appreciate your input!
