Angle Grinder Rectified Feedback

A certain sort of feedback patch on the Angle Grinder has been something of my white whale for the past year. I'm still seeking out that ideal, minimal feedback patch for the module, but there are plenty of fun stops along the way. Here are a variety of noise textures constructed with the assistance of Ears for some additional amplification and the Duatt and Dual VCA patched as a full-wave rectifier.

The core theme across these different Angle Grinder patches has been wave folding—can the Angle Grinder sufficiently fold itself into gnarled, loopy feedback? Can a variety of basic utilities (rectifiers, inverters, ring modulation) transport the patch the rest of the way to that folded feedback? After spending a year patching around a wave folder, I think it's probably about time I put one into the system.
