The Trendmasters "Spooky Tunes" sounds freakish enough prior to being bent. (The first three sounds on the mp3 below are it doing its natural thing.) Along with the practical 1/4" jack and kill switch, the four machine screws act as body contacts for somewhat random pitch, distortion, and glitch functions. It's perhaps the most obnoxious noisemaker in Khate's collection.
The Hellbringah is slated for a construction yellow paint job; but re-assembly after bending proved so tedious that she's loathe to crack it open again. The holes drilled up top are... ah... speed holes.

and hell followed with him
