250K Bourns Potentiometer Replacement for Blues Blaster and Roadhouse mics

Bourns PDB181-GTR04-254A2

250K ohms for Dynamic Elements

You should switch your volume control potentiometer in Hohner Blues Blaster or Astatic JT-30RH Roadhouse microphones when changing to a Shure High-impedance element. The stock potentiometer in the Blues Blaster is 500 or 1000K ohms. That’s too high for a smooth volumes sweep.

For Shure elements:
