This little unit comes with speed control, cassette volume, and instrument volume controls. Also has compress on/off, chorus on/off, and bass enhance (really a high filter) on/off. I used it quite a bit over the years but it's still in great shape although the cheap foam on the headphones has long since gone. I'll include them, but your favorite Walkman-type headphones with a mini-plug will work fine. Will ship in original box. $40 OBO plus shipping, willing to accept trades (stompbox, new set of nickel rounds or flats, etc...) Will post pic later.
