While working in the studio recently I plugged in a cable from an auxiliary send to record some bass and got some horrible feedback. So horrible that I was determined to record it. The reason I was getting the feedback was because the same send that I was using to record the bass happened to be turned up on the channel that I was using to monitor the signal. I realized this immediately, but the sound was quite interesting due to the subtle latency on the signal path caused by the digital hardware involved. Here’s a couple of layers of the feedback running through reverb. I also made adjustments to the pitch a time stretched the recording in a few places.
