Pendulum - Need Faster Rate

[Dirty_Boogie]

Hi Friends,

Just built the Pendulum Harmonic Tremolo, and find that the max rate is far too slow for my liking - the best I can get is about a 1/2 second pulse. I’d like to get it much faster.

I’m guessing one or both of these resistors needs to change?

If anyone else has built this, can you get fast tremolo speeds? If yes, then I need see if I used an incorrect value somewhere.

Thanks!

Solved… replaced R14 (2K2) with a 2K trimpot, and now I can tweak to much faster speeds.

I can vouch for the 2k2 resistor swap. Just built a vero board pendulum, and swapped in a 560 ohm resistor in place of the 2k2 and it definitely cranked up the speed! Thanks for this @Dirty_Boogie !!!
