convert from PNP to NPN

[dachshund]

It seems that in order to use the standard negative-ground power supply, I could switch my tonebender circuit from PNP to NPN transistors. If I swap polarity on the caps and the diode, that should work, correct? The circuit is http://fuzzcentral.tripod.com/3knob.html .

Yeah, I'm pretty sure you just need to switch all the polarized compnents and the power supply.

  Knowing, or having a schematic that's showing, is good.

Yes, I would redraw the circuit with these changes first. Based on the schematic from the URL above, or a similar tonebender.
thanks.
