Here's my Poindexter build. This pedal is one of the most enjoyable things I've built in my life. It creates a huge wall of angry octave-y sound. It also plays evangelical American radio when I stop playing ;D
The extra switch is to swap between 1n34a diodes and red 3mm leds - worthwhile as it allows you to dial in a more modern "chug" sound.

Good idea on the diode switching. If it's okay with you, I'd like to include that as a suggested mod in the documents.
For the RF problem: I don't remember if there is a ceramic at the input of the circuit, but you could add in a 47pF or 100pF in parallel with the pulldown resistor. I do know that RF has been a complaint with some of the Octanes...there is a lot of gain there.

Be my guest! The output volume with the LEDs is insanely high; it is more like a "normal" zvex effect in that it is ear-splittingly loud at 9 o'clock on the volume dial. It's also fun to see them light up when you play. I was tempted to drill holes for them so you could see them lighting up when they are being hit by a signal.
The RF problem is quite fun, to be honest. It is evident in the originals too. Shielded wiring didn't really change anything, either. I may clip on a 100pf ceramic just to see, but I'll probably just leave it.
Hi everybody!
This is my version of poindexter pedal...great effect but, unfortunately noise is very loud! :'(

In & Out under knobs was a mistake...i duplicated layers with photoshop and never corrected! :o
...and excuse me for my english... ::)
