A Atharanic New member Nov 20, 2022 #1 Hi Guys! My Hydra only puts out the delay signal, no original signal. Any Idea what could be happening? Is it wiring? IC?

BryGuy Active member Nov 20, 2022 #2 There is a schematic floating around out there. The dry signal has a pretty short signal path. Just a shot in the dark but maybe a bad blend pot or capacitor https://docs.pedalpcb.com/project/PedalPCB-Hydra-Schematic.jpg Upvote 0 Downvote

Robert Reverse Engineer Nov 20, 2022 #4 Take a look around C2, R4, R9, the Mix potentiometer itself, and associated traces. Everything else is common to the wet and dry signal so can be eliminated as a problem. Upvote 0 Downvote

A Atharanic New member Nov 21, 2022 #6 C2 and R4 reads as expected, R9 reads 9k instead of 15k. And here's a pic! Upvote 0 Downvote
