These resistors set the gain for the hexaphonic fuzz circuit.

For the G, G and G, each string needs two resistors changed, one effecting the synthesizer signal, and the other effecting the hex fuzz signal.The pin out information was correct on the G Service Manual Schematics schematic, which uses almost the same circuits.All the Gs and Gs that I have checked have op-amp pin outs consistent with the G These op-amps are the top three op-amps in line with the pin ribbon connector. The line-level amplifiers are surrounded by resistors for a simple gain circuit, and the hex fuzz amplifiers have the network of diodes used to create the fuzz sound.From looking at the version "A" photo, it appears the one op-amp is used per string to both amplify the signal and create the hex fuzz sound.If you look at IC6, at the top of the version "B" and "C" card, you can see resistors just to the left of the chip creating gain in the negative feedback loop, and additional diodes just to the right side of the chip for generating fuzz.
