For those who might know, what function is associated with the 750pf capacitors at the top of the tone stacks? I know that it will shift the EQ "notch" over and effectively allow more mids through, but which function uses this cap: presence shift, pull fat, etc? There's one on both tone stacks, so I assume that it is the pull fat feature of Rhythm 2 and Lead. The schematic I dug up doesn't show the switching matrix or power supply. Does anyone have a complete schematic for this beast? I'd also like to see a IVb schematic too. I'm curious exactly what was changed between the two. My IVa is knocking on 18 years old, so it's going to be time for a cap job pretty soon. I didn't see any bulging caps last time I was inside, but I know its coming.
