This is a well used Maestro Echoplex EP-3. Was built in the 70's. Relisting due to non-paying bidder. The serial number is 14812 as shown in the second picture. It is missing the top cover. We have tested it and it seems to work fine. NO RESERVE !! Will sell only to the lower 48 states. Paypal only. Thanks for looking and check my other auctions.
