I recent aquired my second delay pedal to use in the loop of my Single Rectifier. But everytime I used it in the loop (parallel), the delays would just sound like a weird vibrato. Almost like the sound is mixing back out of phase or the signal was clipping. Anyone have any ideas? I know its not the pedal cause I tested it on my home practise rig, and I tried a different pedal. I also swapped out the v5 tube. Any suggetion? Thanks guys.
