Straight from the music forum equivalent of the Freemasons, without the funny handshake but your membership can be black-balled. The original has a trimmer for gain but I have put this as an external pot for my own personal preference in muff-like pedals. If you’d prefer to keep it authentic then remove the wires and either put a long lead trimmer in there like the Alps RH06, or using flying leads and have a little gain trimmer daughterboard like this.
