Metasonix TM7 Ultra-Distortion Scrotum Smasher
Metasonix TM7 Ultra-Distortion Scrotum Smasher features intentionally vulgar control options based on distortion and power; Smash, Scrotum, Double Scrotum, Mega Scrotum, and Scrotum Up Ya Ass." Audio Geek said of it, "The TM-7 is basically a mean, angry guitar preamp made of three vacuum tubes. Plus a feedback loop which makes the preamp unstable. There is nothing else like it."
