I only use “Normal” guitars. Headless yes, and in one video I tried the Hex PU, but other than that always traditional guitars with ordinary humbuckers. Breathcontroller is a separate system just for expression control (I also sometimes use a fretless Vigier that has both a sustainac and a GK-mic on it, but I still use the standard magnetic PU there as well, whenever I play MIDI Guitar 2 stuff)
