It was all my bad, I was using the wrong power supply. Sorted now, with many self-facepalms.
I had this same problem, and posted it up here. Actually that’s the reason I found this thread – I was looking for mine to say that I got it sorted out, and it was entirely my fault. I was using an adapter with too high an output, and it made the pedal useless for what I wanted. So, yeah, make sure you’re using the right adapter. If it isn’t working, then try a lower output.
Yeah, that helped, but only just. It’s still not at 550, and this is getting to be a pretty serious problem, because I have no use for a short, almost slapback delay. I’m going to send it back to EHX and see if they can fix it, or replace it.
Thanks, I’ll do that.
