High quality Swiss-made collet knob for Alembic basses and guitars. Pry off the cap with the white indicator line and loosen the collet with either a 6mm nut driver or a large blade screwdriver. Do not attempt to pull the knob off without loosening the collet first or you will destroy your potentiometer.

1/4" shaft size for everything except early Epics, early Distillates, and early Spoilers, which will need the 1/8" shaft diameter.
