  Sourcing Concentric Volume/Tone pots for Sire Marcus Miller Bass

  Posted by Casey Murray Casey Guitar Repairs on October 22, 2024 at 5:36 am

  I’ve had a customer bring in a Sire Marcus Miller with a faulty volume pot. Currently I have an alpha concentric pot installed but it’s too big for the cavity with all the wiring, pre-amp etc. and the knobs don’t fit the shaft. I tried using insulation to widen the shafts but the discrepancy between the centre of each knob (Upper and Lower) has them bumping up against eachother and moving in tandem.

  Does anyone know where to source this part, or similar?
  The main part would be the split-shaft upper knob, which is needed to attach the Sire knob.

  Does anyone have a workaround to continue using the Alpha pot with the original knobs?

  Original pot measurements:
  Lower shaft is 8mm
  Upper shaft is 6mm
