HGE Contraptions Catalinbread SFT II clone (124th pedal built)

* HGE Contraptions Catalinbread SFT II clone, with the stoner switch. Very cool QOTSA sounds from this mean od/fuzz thing. I used Motorola MPF4393 transistors as per the original.

(124th pedal built)

IMPORTANT Later Edit!!:

In the meantime I discovered a general error that existed for this schematic on the web, and corrected it for the owner. Now the Gate from the Q1 position FET is seeing a stable voltage. This is totally wrong online and I will do my best to alert anyone who does this to correct this. Basically moved one leg of the 470K resistor at the input 2 rows down(at the other side of the 100nF resistor). <photo below circled in blue>
