Hi, I'm working on some Scorpions songs, and dig Matthias' pinch harmonic squealies. I kind of luck into a few, but I'm having trouble getting them consistently. I have a Strat with a Super Distortion HB bridge pickup, & play through a Mustang 1 with a lot of gain. I've tried choking up on the pick,but still kinda inconsistent... Any advice? Thanks!
