Hi Daryl
A long time to reply... but I was reading this thread and realised that the feedback loop value change could be beneficial after all.
The gain is set by 2k7 / 47R = 57.4. Even though the closed-loop gain is high compared to the nominal open-loop gain of 100, the resistor values are low, as is typical for Fender. Going to 27k and 470R could open up the sound.
In general, when the loop is "opened up" to allow more actual voltage gain, say fro 9.2x to 20x, the sound will be a bit looser, maybe with less-damped bass. The value change without gain change gives a different dynamic feel, going from a "dry" or "choked" tone to one that is more "lively".
