Yeah, I have reduced the Feedback and it haven’t had that problem since. I guess i was initially stumped to see that even after I had bypassed the unit, the sound would come back when I engaged it again. It definitely seems like I have to be more careful with the feedback knob when I am playing around with the pedal.

So I think i finally figured out what is going on, and its probably a lack of understanding on how this pedal operates, but here’s what I realized.

If I unplug (power off) the pedal and power it back on, the pedal starts with no noticeable feedback or noise. It’s only after I’ve been using it for a while, changing tempos, disabling, enabling it again, that the sound becomes “dirty” if you will. Slowly but surely this high pitched noise will start accumulating in the background, probably a byproduct of the delay and feedback feeding on each other until it becomes noticeably loud. The only way to get rid of it is by unplugging the pedal and plugging it back in.

Is this normal for analog delays? Or is this something weird?
