Boss XT-2 Xtortion
Super badical high gain distortion pedal. Not a very common one. This one packs a ton of nasty 90s grind, with controls for Level, Contour, Punch and Distortion.
If you're wondering what 'Punch' controls, look no further than this handy excerpt from the owner's manual:
PUNCH: This adds "punch" to the distortion. Rotating it clockwise will give the sound more punch.
There you have it.
