Adding an LED to a simple fuzz face circuit WITHOUT a 3DPT switch?

Hey guys,
I finally got my Fuzz Face to work (I posted a question about it before) and it sounds sexy sweet.
Now I want to add a status LED, but I only have a DPDT switch. I can't make millenium bypass, because its a positive ground circuit, but is there another way?
Or do I just buy a 3PDT switch?

Thanks!

You can if you use a p-channel JFET.

Yes, there is a "how to" on geofex I think, I used a millenium for a positive ground FF...

You can use a regular mil bypass pcb and reverse diode placement with a P channel mosfet (or jfet).

Is a 2N5460 JFET any good?
And, so I should just flip the diodes/LED on this circuit?

  Actually that's not exactly true, especially when many LED indicators need to be monitored, all my effects have indicators now.
  3PDT's are nice and easy.
  Glad to hear the PS short got sorted out, and that caused the FF to begin work.
  Another option, as you probably well know: NPN FF, Neg Gnd.
