I have a big box DMM that’s not sending out echoes. I’ve had the pedal about 6 months and haven’t had any issues until Sunday. If I smack it, the repeats come back for a bit. Eventually though, they fade away. Any thoughts? It was calibrated by Analogman at one time, and like I said worked until last weekend.
it sounds like a connection problem. maybe a cold soldering on the pcb. or even bad potentiometer
you should start checking all the wiring and redo the soldering on the pcb
if the problem persists, then you will move on to do some further testing
keep us posted
THat would be my guess as well.
