The Fender TBX (Treble Bass Expander) is a detented, stacked 250K / 1-Meg control that enhances your tonal palette without the use of a battery. From "0" to "5" the TBX is your standard tone control, but once you pass "5" you start to decrease the resistance which allows more bass, treble, presence and output to flow to your amp.

Top quality potentiometers used on American Fender® instruments. 3/8" potentiometer shafts. Mounting nut and washer included. Split shaft for compression fit knobs and solid shaft for set screw knobs.

Each TBX Tone Control comes with a .022mf capacitor, 1-Meg resistor, White Tone Knob, Mounting Hardware and Installation Instructions.
