Description
A stacked concentric potentiometer — two separate pots on one shaft, controlled independently by an inner and outer knob. This is the same style of control found on some vintage-reissue Jazz Bass wiring, where a player needs two controls (like separate neck and bridge pickup volumes) in the space a single knob would normally occupy. The 250K and 500K values are split between the two stacked pots, matching different pickup types on the same instrument.
Benefits:
- Two independent controls in the footprint of a single knob
- Genuine CTS quality in a specialty format not commonly stocked elsewhere
- Correct fit for USA-sized knobs, designed for easy pickguard mounting
Features:
- 250K/500K ohm, audio taper
- Solid brass shaft (upper: 3/16" diameter, lower: 1/4" diameter)
- Includes mounting nut and two washers
Specifications:
- Overall dimensions: 1-3/4"H x 7/8"W
- Weight: 28 grams
- Bushing thread: 3/8"-32
Installation note: this is a more involved wiring job than a standard single pot — professional installation is recommended if you're not already comfortable with concentric pot wiring.
