G&L tech resources: Wiring harnesses

 
 

The ASAT ’50 is one of the Buffalo Brothers Limited Editions designed by Tim Page and, at the time, exclusively distributed through Buffalo Brothers in Carlsbad, CA. Its wiring harness is based on the early-1950s Fender Esquire as depicted in the schematic CLF Research posted on Facebook. Although appearing on CBS stationary, the original was drawn on April 12, 1962, still more than a decade removed from its first use. A slightly different version is found on the Telecaster Discussion Page Reissue forum using 47,000pF (.047µF) capacitors instead of 50,000pF (.05µF), an insignificant difference given the tolerances. The 3-position switch in position-1 only engages the CTS 250kΩ Audio Taper volume potentiometer, which also works in any of the other positions. The CTS 250kΩ Audio Taper tone control, with a 50,000pF (.05µF) cap from wiper to ground, is only engaged in position-2. Position-3 engages a fixed frequency filter consisting of a star circuit with a 50,000pF (.05µF) cap to ground and a 3.3kΩ resistor in series with another 50,000pF (.05µF) cap connecting the terminals for position-3 on the switch. The ASAT ’50 is from 1999 and it took until 2013, 14 years later, before G&L issued its own single pickup ASAT, both in a version using an ASAT Classic Magnetic Field pickup as well as one with an ASAT Classic Alnico pickup. The Paul Gagon designed wiring harnesses on the ASAT Classic Solamente and ASAT Classic Solamente Alnico are identical. The volume control is a 250kΩ Audio Taper pot with a 200pF ceramic treble bleed cap. In position-1 of the 3-position switch, this is the only control engaged. Position-2 adds the 250kΩ Audio Taper tone pot in series with a 1kΩ resistor to ground, as well as a 22,000pF (.022µF) treble bleed. In position-3, instead of the tone control, one engages a fixed frequency filter consisting of a 3,300pF (.0033µF) cap to ground “... to shift the resonant peak of the pickup” thereby adding warmth. Note that in position-2, ignoring the 1kΩ resistor, one has the same ASAT Classic tone stack as before.
