Well... I did it again. I found this amp listed at a shop nearby a about a week back. After looking at it and hearing sound clips of the 210 music man models, I had to check it out! Took my 1972 Twin Reverb with me, just for comparison sake. It's tone is great, and it is pretty loud! The shop purchased this amp from the original owner, who said that they got it when Music Man amps were first released, and pretty much just used this amp at home. The amp is all original, including the speakers, footswitch, tolex, grill cloth; I think it even has the original tubes in it! Looking at the amp, I was told by the shop staff that it was a 1973/4 amp (I thought music man amps were first manufactured in 1974?), which meant it could have been one of the first sixty-fives built! I will take it to the tech, though, to have it looked over before I take it on a gig (especially checking the caps!). Here are some shots of it, (of course). The color of the grill in this picture is a bit misleading. It actually looks almost as new as my 65 DRRI. Took off the back panels to get a better view on the condition of the original speakers. Tube chart! I think it has 6CA7 tubes in the power section right now. As far as I can tell: the inside of this amp is really clean! I will ask the tech to check everything though and make sure we're within specs. Finally: here it is with my 1972 Silverface Master Volume Twin Reverb.
