Telecaster 3-Way Pre-Wired Control Harness



*Please allow up to 3-5 working days between build time and postage.

Standard Tele harness is supplied with an EWG Treble Bleed/Volume Mod.

Left-handed harness comes with reverse audio CTS pots but with split shaft pots. As I can’t find solid shaft pots for this purpose, this harness will be sent out with brass shaft adaptor sleeves which is a good workaround to allow you to use your existing 1/4″ sized metal knobs.

Fender Telecaster pre-wired control harness with 50’s Les Paul wiring modification. Two simple solder connections required. Drop in upgrade for Squire and Affinity Tele’s.

**Can be supplied with crimp connectors for solderless hook up if required. Please leave me a note with your order if you require this.**

Kit includes:
• TAD Custom CTS Solid Shaft (audio taper/logarithmic) potentiometers (Matched)
• Oak Grigsby 3-Way Switch
• Switchcraft 1/4″ Mono Input Jack with pre-wired harness using twisted vintage push back wire enclosed with heat shrink tubing and also used on connections for strength
• Soviet Union NOS 0.047uf/47nF K42Y-2 Paper in Oil Capacitor (Tested within the ± 10% range)
• Professionally soldered using vintage push-back wire.

**Switch Tip and Control Knobs Not Included**

What’s so special about this ’50s wiring? It affects your tone in three major ways:

1. The overall tone gets stronger, tighter, and more transparent. It’s difficult to describe, but you might say it’s more “in your face.”
2. The typical treble loss that occurs when rolling back the volume is much less than with standard wiring. Both the volume and tone controls become more responsive, and they react more smoothly without the usual hot spots. Another bonus: By simply rolling back your guitar volume a bit, you can clean up an overdriven amp without getting lost in the mix.
3. The tone and the volume controls interact with each other—something you might be familiar with from certain tweed-era Fender tube amps. When you change the volume, the tone changes a little bit as well, and vice-versa. This may be strange at first, but you only need a few minutes to get used to it.

The ’50s wiring exhibits much less treble loss that standard wiring because it follows a completely different curve, depending on the ratio of your pot. It works best with audio taper pots, preferably those with a 60:40 or 70:30 ratio. Smaller ratios like 80:20 or 90:10 limit this benefit and result in the typical “on/off” or “bright/dull” problem when using the controls.
