 how to buy

XTCT is similar to the original TCT on-board preamp, but it has a mid-frequency notch at 500Hz for slap tone with more bass. The XTCT has Bass, Mid, and Treble controls with very low noise and wide adjustment range. It has vintage FMV (Fender/Marshall/Vox) frequency controls so each band affects the others and if all bands are set to minimum, the output is muted. The XTCT preamp has a voice of its own, providing vintage color to your sound. XTCT is based on the original TCT preamp with inter-dependent controls, so it is a tone shaping preamp rather than a strict EQ and requires expertise.
A professionally pre-wired and fully pre-tested harness saves the time and aggravation of wiring your preamp and pots into your instrument. Wired with our pro-level preamp and premium audio-quality pots and switches, you’ll have smooth control and be ready for years of rugged use. We include battery clips and an output jack for quick installation. All the pots are grounded with a wire that can be connected to the cavity shield or simply cut away if not needed in your installation. Everything is pre-soldered with pro-quality pure copper wire that is double tin plated and protected with semi-rigid insulation so it won’t flop around in the cavity or degrade over time. We use only professional lead-free solder with non-corrosive flux. Knobs are a personal choice, so they are not included with the harness – except where there is a stacked (concentric) pot, we include a ring knob and center knob since they are not as common.

Bass Control

  • Boost or cut your low frequencies. The control is assymetric and somewhat affects treble response as well.
  • Bass: +/-12dB@50Hz

Mid Control

  • Thicken or thin your tone with mid control. XTCT has native mid cut for classic slap tone. Pull the mid to set the mid frequency boost to 250Hz, or quickly push to 750Hz for a solo.
  • Mid: +16dB@250/750Hz, -11dB@500Hz

Treble Control

  • The XTCT provides ample control range for treble boost or cut. The control affects bass response as well.
  • Treble: +/-13dB@6KHz
