Leprechaun - Strange Glitch

The Leprechaun (EQD Rainbow Machine) is such a weird, extraordinary pedal! I called mine the Frobozz Machine after being inspired by the recent Zorkmid pedal (which is PHENOMENAL, by the way). Unfortunately, my Leprechaun has a WEIRD QUIRK. The dispersion knob function (which affects the lengths of the repeats) goes up or down randomly. I'll set it where I like, but it changes on its own after a few seconds. Do you think this is a glitch? Could there be something wrong with the programming?

The schematic isn't in the build doc but as far as a can tell looking at the board that pot does not directly control the FV-1. This pedal also uses one of the internal programs in the chip so the programming is there from the factory. I am betting on a poor solder joint or bad pot.

Interesting! Thanks for the tip! I'll check the soldering on the "dispersion" pot again and break out the ol' multimeter for the pot itself. Thanks!

I checked and it appears that the "dispersion" pot is soldered well and seems to be working fine, according to the multimeter. Does anybody have any other guesses as to why it resets itself to seemingly random intervals after I get it dialed in?
Thanks in advance!
