SiliSmile w/ PNP?

[Pt67]

I'd like to build the SiliSmile Fuzz with PNP transistors. After studying the difference in fuzz faces, pnp vs npn, am I safe to assume that I can reverse everything that has a polarity, starting with the power source, the electro caps, the diode and led? Thank you in advance!

What will be your power source?

Battery will isolate the PNP SiliSmile from your other pedals but swapping out batteries is a drag to do and a drag on the environment.

I suggest going with Robert's charge-pump / 3PDT daughter board. Then you can plug it in to a regular ol' pedalboard PSU with +9v Centre-Negative.

Same as Feral recomends or.....If your set on using pnp I'd recommend the Sunflower https://www.pedalpcb.com/product/sunflower/
you'll automatically have the charge pump implemented to use regular power plus some extra tweaks to the fuzzface circuit..
