I bought a BOSS DS1 in 1978 and its still going but........ the rubber grommit where the little screw goes into the pedal has perished and its making the operation a bit hit or miss - can I still get just the little bit of rubber?
Decided against this as when I press the footswitch the signal is cut momentarily and I don't like the gap - about to explore a non BOSS solution to the problem.
