semi parametric eq - noise

[tuckster]

Hello lovers of the new forum design,

I recently built a nice pedal from GCI and I have a nasty noise on the high control of the semi parametric eq part of this "pedal" (in terms of monster pedal).

Turning the high controll to ccw to min gives a nasty noise. The noise is noticable from 0 to like 3 (10 o'clock).


On pin 2 & 3 of IC8A everything is fine. Is there something I can check/swap/tinker?

Tyy to place a resistor (of trial & error value) between lug 1 and IC8A output..
