Fender TBX (Treble Bass Expander) Tone Control Potentiometer Kit
The TBX control is not any standard tone pot! The stacked pair of 250k and 1Meg pots work together to decrease resistance as the control is turned above '5'. This sends more bass, treble, presence, and output to your amp - hence the name 'Treble Bass Expander'. This tone is incredible!
In the kit:
- 250K/1Meg potentiometer
- White "tone" control knob
- .022mf capacitor and 1/4-watt resistor
- Mounting hardware and installation instructions.
