FenderTBX Tone Control
Independent shopping perspective
The Korena take
Replacement tone control for Fender-style guitars with an expanded sweep. For players who want more range from the tone knob than a standard pot gives.
Strong match
Who this is for
- Strat or Tele players who find the stock tone control too limited
- Anyone already doing a wiring harness refresh or pickup swap
- Players who want treble boost as well as treble cut
Consider the trade-offs
When to look elsewhere
- Anyone who cannot solder or does not want to pay a tech
- Players happy with a standard tone control's range
- Guitars with active electronics or non-Fender control layouts
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Center detent
The knob clicks at the neutral position, so you can find flat by feel without looking down mid-song.
Detail 03
Fender-spec control
Designed around Fender pickup and pot values. Behavior on humbuckers or other pickup types will differ from the intent.
Detail 04
Soldered installation
This replaces the existing tone pot in the harness. You are removing wiring and reflowing joints inside the control cavity.
Detail 05
Under twenty dollars
The part is cheap. If you pay a tech to install it, labor will cost more than the control.
Final check
Know before you order
- 01Knobs are a separate purchase — your existing knob may not fit the stacked shaft
- 02No wiring diagram assumed; find the correct schematic for your guitar before starting
- 03Check your control cavity depth, as a stacked pot sits taller than a standard one
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I install a TBX myself?
If you can solder and read a wiring diagram, yes. It replaces the existing tone pot. Budget an hour and work carefully in the cavity.
02Will my existing knob fit?
Not necessarily. The stacked design uses a different shaft arrangement than a single tone pot. Check the shaft type before assuming your knob transfers over.
03Does this work on a Telecaster?
It is built for Fender-style single-coil circuits, which covers Tele wiring. Confirm your cavity has room for the taller stacked pot.
04What does it actually sound like?
Below center it works like a conventional tone control, rolling off highs. Above center it opens the top end past where a standard pot sits.
