The following wiring diagram shows a mod I'm planning for my Strat Plus. In addition to providing new pickup switching capabilities and active mid boost, it should also bypass the mid boost circuit completely (true bypass) and allow pure passive operation. The mod uses two S-1 switches, a Fender Superswitch, and a TBX tone control. The first S-1 controls master volume and the switch selects between standard switching and Hermetico's American Deluxe SSS mod. The TBX is a master tone control for both active and passive modes with Doc's TBX mod. The second S-1 controls the mid boost level in active mode. When the switch is up, the active circuitry is completely bypassed and the battery is switched off. When the switch is down, the active circuitry is engaged and a 68K ohm resistor is placed across the master volume control to simulate a 50K ohm MV control (for the mid-boost circuit). (Actually, the correct resistor should be 62K ohms, but 68K is a standard size and should be close enough.) I've been looking for a good circuit description for the mid boost with pinouts to verify that all of the bypass connections make sense, but haven't found one yet. This is as close as I've been able to get based upon the generally available mid boost wiring and circuit information. Does anyone have a description of the mid boost circuit that shows both colors and functionality on each of the I/O connections? I haven't built it yet, but will as soon as I'm sure it will work. Does anyone see anything that won't work? Thanks. By the way, huge thanks to Andybighair, Hermetico, Doc, Alan0354 and WalterW (true bypass info), and others who have contributed to my education on how to do this.
