Oh, that's a massively large value; very cool. I never considered that you could use regular old caps and resistors on active pickups to shape the signal like you would on passives, just with different values. I actually have an EMG 85, a Duncan Blackout AHB-1, and the Duncan Blackout AS-1, which is their "single coil." Now I'm wondering about what I could do with those.
Recently I've gotten into shifting the resonant peak of passives, and I just assumed you couldn't do that with actives, but now I wonder. Since you're brightening the signal on rollback with the cap, I guess it's probably the same as a cap only treble bleed on a passive pickup, where it blocks lows at a certain cutoff point.
With passives at least, if you go to really low cap values, like below 100pF, the same bleed that was just blocking lows starts actually to shift upward the resonant peak! This is a really cool effect, and you can tame it's effect with a resistor. So I wonder on an active if that's possible.
But bigger than that, I'm interested if you can shift downward the resonant peak on an active. I do this now on my passive bridge, which is very harsh, but I run a 2.2nF cap in parallel with a 220k resistor between the output lug and ground of the volume pot, to have a big downshift of the resonant peak when the volume is at full, then for that shift to go away as I roll back; it works with a treble bleed too.
Anyway, you got my wheels spinning here. Thanks for the inspiration!
