Double Pendulum Harmonic Tremolo

Finally finished this one tonight. It's been on the workbench waiting for a C50k pot that I could've sworn I had already ordered. No issues putting it together, socketed the LED's and the LDR's in case I wanted to experiment with different parts. Sounds good and has been added to my smaller board. Waiting on some new acrylic markers in the mail so I can label it.

Nice build! I dig the gold enclosure. Excited to get to this one.


Got one today Where can I find the BOM?
Start from the single pendulum docs. They seem to have worked for those who came before us.

I imagine there's a drill template kicking around though.
 
Its been a while and I don't remember if I used one or just read the values off the PCB/from the image here:

Forgive my ignorance but would this pedal allow me to input a mono signal (guitar) and get a stereo panning effect? Are the L and R tremolo effects 180° out of phase from each other? If not, what's the point of this stereo tremolo? Is it just two independent Pendulum Tremolo circuits in one box?

Yes, the modulation is out of phase between the Left / Right channels.

And yes, you can use a mono guitar input and get a stereo output. It'll also accept a stereo input.
 
For Mono > Stereo you'll want a switching jack for the Right input. (I use switching TRS jacks for everything, just for convenience)

Connect a wire from the Left Input jack Tip to the Right Input jack Switched Tip.

This will send the left signal to the right channel when no cable is plugged into the Right input.


These are the type of jacks I use:
