This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Mid-Fi Electronics Pitch Pirate

Here's the Pitch Pirate with board mounted pots. Like the Deluxe version, the LFO is designed to be grounded when the effect is turned on (hence the pad at the top of the board). Just use the true-bypass wiring diagram in the General Layout Notes and leave out the LED wiring. Then just connect the corresponding pads on the board to the lugs of the switch. The on/off indicator LED (pads at the top of the board) is connected to the LFO ground so that will turn on and off (and show the rate) with the LFO. It'll fit just fine in a 125B with top mounted jacks, but will also fit in a 1590B if you wire the pots off board (or maybe with long leg pots mounted to the component side? YMMV).

  1. Kinda quiet around here... weird.

    Thanks for the interesting selection of layouts as of late. I may try this one just to do something unconventional! Man does not live by fuzz alone...

  2. Thanks for this. But something wrong with the transfer image, something like the pdf file is corrupted. Anyone experience this?

  5. i am a true beginer with electronic things but I suggest to try with other tl072 and/or lm386

  6. Built this one tonight. Just like the Deluxe version, it's very picky about chips and vactrols. I ended up with a 5mm super bright red LED and one of those Tayda Waitrony LDRs for the vactrol. I must have tried over a dozen different combinations. Sounds just like the video, thanks so much for the layout. I have also built your version of the Deluxe, it's one of my most-used pedals.

    2. Hey nice to hear someone messed around with it more than I did. I've built the deluxe version but it never worked and I'm awfull at debugging (for now). Any chance you also encounterd wet only signal and ugly glitches instead of nice modulation due to bad chips or bad chip combinations? That's all I get with mine, controls do respond but nothing sounds as it should.
      -Again this is about the deluxe version

  7. I found a VTL5C2 in my parts stash, so I popped it into this circuit. IMO, it's even better than the 5mm red LED & LDR combo I had in there previously.
