Works fine. Does have some noise due to being vintage but wouldn't be audible while playing in a band.
Appears to be a prototype ("Sample") from 1979, signed/etched by the engineer/maker on the inside of the faceplate. Very quality compared to today's crap. Uses CTS pots (dated 1976 and 1979) and Switchcraft jacks. Non original handle. I do not have the foot switch.
