Schematic: EH 7810 schematic.

Pete of Pete’s Pedals shared with me some photos of a PCB marked “EH1338A”. Comparing to the EH-7810 schematic, this PCB is missing the missing trim is the “HIGH FREQ” 100k pot that forms a simple one-pole passive RC filter with a 4.7 nF capacitor that precedes the active low-pass filter. This PCB also has a 1 uF electrolytic at the bias pot wiper.
