    Sproing Deluxe - no Tremolo

    Yes, the three LEDs were backwards. Somehow I had all three backward, despite triple checking the meaning of the square pad vs round pad, A vs K, and still writing it out correctly on the initial post. :oops: Good news is, I got everything switched around and the effect works. Thanks all!

    Sproing Deluxe - no Tremolo

    Hi all. I ordered and built a Sproing Deluxe PCB - after emailing to ask for a bill of materials and being advised that all values were printed on the board. Great!

    Bypass sounds fine, no sound with pedal engaged. Even with the amp turned up you can't hear anything (including pot sweeps).

    Hi all, Working from this layout of the Precipice schematic. The only part substitution I used was a 1N4001 in the rectifier spot instead of the 5817. I've tested between all the vero rows for shorts, double checked component placement and trace cuts, and I'm stumped. IC voltages are 1:7.39v...
