with the guitar coated, on to the electronics. I like to create unique circuits with my guitars, and for this build I created a simplified take on the Varitone switch. Its a 3 way rotary switch giving:
1. full sound
2. extra treble reponse by cutting some bass and shifting the q higher
3. warmer sound of a low-value pot with the tone knob rolled halfway off
see the circuit and photo below. I experimented with component values until I arrived with a circuit that sounds subtly different, but very nice with the stock humbuckers. The bright setting is good for lead and ambient playing, while the warm setting is great for jazz.
I also installed small terminal blocks in the pickup cavities, so I can swap out pickups without extracting the full wiring loom.
The other mod I did with the wiring was to drill a hole through from the strap button to the control cavity, so I could ground the bridge and strings.
Speaking of the bridge, when I bolted the Bigsby down I found that the metal bent to the contour of the body, so no worries there.
