A Supa Tonebender in near mint condition, giving a very weak output signal.

Guts reveals what appears as all original.

Signal generator and a scopemeter isolated the problem to the bypass switch.

Not the typicall bypass switch construction. Note the date stamp 10 MAY 1976.

However a construction that is easy to service.

After a cleanupof the switch and the Radiohm potentiometers, the pedal is back in working condition.
