Built out this dual pedal with a PedalPCB Amentum into a GuitarPCB Green Russian Muff’n. Total doom box. Really love it and how it turned out! Used GuitarPCB BC549Cs which you have to flip backwards for proper pin out. Also used the SPDT On/Off/On switch for clipping modes. Used red LEDs, 4148s, and 4001s. Fun build!
