This pedal kicks ass for noise. Another one of those only useful for noise DOD pedals that was discontinued. The most unbelieveable rumbling lows are possible, ala early Dan Menche.The "Meat" controls the amount of sub-harmonic signal vs. dry signal, the "Rump" controls a 30Hz boost, "Flank" controls a 60Hz boost, and "Lbs." controls the output. The Meatbox pedal will shake the paintings off the walls because it creates sub-harmonic tones.
