Does anyone have or know where I can get a TYCOBRAHE PARAPEDAL schem or layout??

I'd love to build one of these but the schematic has eluded me thus far maybe one of you has had better luck

thanks all

Good R.G. Keen work

I built one a couple of weeks ago using the smallest layout from geofex on perfboard. Works great and has a pretty deep wah type effect. If you do a search there are a couple of potential mods, I tried changing one or two of the caps to alter the sweep/depth but preferred the stock version.

Any tips on finding a dual 10K pot w/a long shaft? Didn't see any at Mouser-

I have been using a dual 100k with a 12k resistor across it. works fine. You could use any dual pot above 10k and wire a resistor across it to give you close to the 10k

Smart! Hadn't thought of that. There's a surplus place here in town, if I can find a long shaft dual pot that should do the trick.

I have one of the DIY parapedal kits. The thing that I "dislike" the most - is the sweep of the pedal. I don't really like the "full off" at the top (full rock back). Any ideas on increasing the sweep ?

Thanks, Dan

What did you use for C3? (it's not on the GEO schematic anywhere)
I think it is somewhat optional but curious to know what I can find out about it.

Thanks

I used a 0.01uF cap for C3 on my Parapedal clone.

Thanks Paul
Did you get this off another (different) schematic. Curious what the cap does.
Looks to be a high/mid pass filter...although 1K is pretty small for that ...
