Fixed The Noise Issue!
I recently purchased an older "big box" EHX holy Grail and use the 1Spot daisy chain to peer all my pedals. Although it came with an adapter for their older input, there was this unbearable, ringing noise that I couldn't get rid of, regardless of how much EQing I tried (plus moving it around my pedalboard, trying different power strips, etc.). Once I ordered this though, and received it, all my problems were solved, and I can record and perform with this thing without a worry!
