    Can someone tell me which caps on the Muff’n are the coupling caps and the caps for the diodes? Thanks!

    See the schematic.  Coupling caps are C3,C7, C12, and C13.

    Caps associated with diodes are C6, C9 and C8.

    I am currently working on the 2020 Build Doc updates and will be updating the Muff’n soon.

    In the meantime here is an updated schematic with values added in.

    I myself would be interested in placing C13 (100n) on a switch and try going between stock and say 10n or 22n to act as a “Tight” switch since Muffs do tend to get a little flubby in the bottom end. I already know that a Tone TwEQ is a great add-on board for this circuit.

    Thank you both! I’m currently in the process of planning to build a hybrid muff between a Triangle and the Green Russian.

    Here is the new wiring diagrams.

     

    There is more than one way to wire since we have multiple pads convenient for using Add-On boards such as the Tone TwEQ so as long as it gets the job done.

     

    Here is a populated board image mostly following the Rams Head with LED Clipping. (Must Try)
