Pressing low end that’s almost too heavy to hold, The Mantic DENSITY HULK power-lifts sub tech to the next level.

Heavily inspired by the infamous 1995 DOD Meatbox and DBX BoomBox, the DENSITY HULK flexes improvements over the original that make this box more juiced and road-ready than the Tour de France: a heavy-duty footswitch for clean, true bypass switching, Alpha potentiometers, the modern standard 9v barrel power jack, premium hand etched PCB populated with top-shelf components. Each Density Hulk is completely hand soldered, wired, assembled, and tested in the U.S.A, ensuring military-grade reliability certain to withstand the ‘roid-raged rigors of even the most hypertrophic of tours.
