Anyone know if the pinout for the FETs is still backwards on the board layout?  I read that it was, but, it was quite an old thread.  Would certainly explain why my pedal ain't phasin'...

Looks right to me. If you are using this layout:

Are you using Fairchild 2N5952s for your FETs?

Ok then, thanks!

Yes on Fairchild.  Got them from mouser.  (just bought 2 because i knew nothing about matching them.

Matching the FETs is a MUST in my opinion! Definitely read about and build the Geofx JFET matcher. You will probably need to order more FETs.


Good Luck  ;D

Thanks.
Yeah I found te schem for the matcher, but I'm not much on reading them yet.  I'm having trouble seeing how the opamp is connected.  I do better with layouts for now... :icon_mrgreen:  I can hear a ticking that is controlled by the knob, but, other than that, its just dry guitar signal...
