What is TBX wiring?

Traditional tone pots give you a range from 1-10. A TBX tone pot will give you a treble and bass boost while remaining a completely passive instrument.  Your standard tone control goes from 1-5 and from 6-10 is where the TBX kicks in. Giving you more treble and bass to your tone. The Fender TBX tone pot is stacked and dented so you can feel when changing over from your standard tone control in the 1-5 range, through to the treble and bass extender in the 6-10 range of your tone pot. This decreases resistance, sending more bass, treble, presence and output to your amp.
