IdiotBox Dungeon Master Overdrive Guitar Effects Pedal

Part Muff, part SuperFuzz and part HM-2, the Dungeon Master sounds exactly like you want it to. Sludgy and doomy as heck but still clear enough to not sound like total mud. 
Tons of volume, tons of gain, tons of sustain and tons of character. 
Run it full blast on the controls for maximum slaying or dial back some on the DRIVE, LOW and HIGH controls to get that unique heavy as balls sound you've been after! 
Newer small version is exact same circuit as large version in demos.

SPECS: 
Smaller 4.7" x 2.6" x 1.5" 125B enclosure, true bypass switching, common 9vdc center negative BOSS style power input and battery snap. Current draw 10mA. Power supply not included.
