I have a vintage YAMAHA Integrated Mixer/Amp EM-85. Its been tested and everything works like brand new. This thing gets real loud, with volume all the way up there wasn't any signs of distortion. crystal clear mids with YAMAHA signature 'thumpy' bass. It's unfortunate that I have no use for it. For a STEAL you can make this a part of your setup $100 or best offer, Binghamton meetup/pickup only cash or cash app is accepted.
