Here's a problem I'm having with a newly acquired delay pedal that gets glowing reviews. I'm scratching my head because I can't be the only one who's noticed it. The builder says it's normal for analog circuits so it's apparently not defective. I'm not going to name names because I don't want to start bad-mouthing, rather just a scientific survey to clarify things. Noise--particularly hissy, sputtering sounds synced with the delayed signal. Like you can hear it working. Not real loud but noticeable enough to be really annoying, particularly for recording. It's more noticeable the longer the delay time since there's more space between notes to hear it. I'm really disappointed as I had high hopes for this pedal and am sick of trying things and sending them back.
