Your volume or tone control has drifted, the old pot's worn out, and you need a log taper back on the board. This Jaycar 50K ohm logarithmic (A) single-gang potentiometer drops straight in. The 1/4" D-type shaft is 30mm long, so it clears your PCB and still takes any standard knob without trimming. Log power rating 0.1W. Sorted
