This polytone is from around 1978 one of the Golden Era polytones. Everything works. I just had the reverb replaced at Bay State Vintage Guitars and the speaker cover (not foam tolex...this era did not have the foam covers that notoriously rot). Only getting rid of this because I have too much gear. This is that quintessential Joe Pass vintage dry tone. Here are some videos of me playing the actual amp on my YouTube Channel. No trades and no low ballers this is NOT one of those beat up poltones.
