Are the snaps “effected” or coming after the wet effect?

Here’s another part of it. It may only be happening when I’m running wet/dry. I’m only hearing it on the dry channel (no matter which amp I use for dry), and it does go away when relay bypassed. It’s still present for DSP & DSP+FX bypass, though. I’m going to stay in mono for a couple days and see if it recurs.

Is there any accounting for why it might happen in wet/dry or other stereo modes, but not in mono? It’s not a ground hum; it’s an irregular staticky crackle. And it does go away in true bypass.

I appreciate you helping me work through this.
