From the post
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).
