Handcrafted Tele Wiring Harness w/TBX Tone Control – 3-Way Switching


You bring the talent. We’ll supply the kick ass wiring…   


Hoagland Custom, located in sunny Fernandina Beach, Florida, has specialized in custom guitar wiring and pickup making for over 25 years and we love what we do!

This Tele wiring harness will give you an EXPANDED TONE CONTROL.

This harness features a Fender brand TBX Control. TBX stands for “Treble Bass EXpander”. It was introduced by Fender in the mid to late ’80’s. Fender’s own description of it is as follows:
“This detented, stacked 250k/1meg control 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, and presence and output to flow to your amp.”

Lots of mystery surround this tone control but there’s nothing difficult about it. It gives you a greater range of tone control than a standard pot can give you. More highs. More lows.
