The Earthquake Revolution Mark II (EQ-2) bass wah delivers the same killer performance of the Silver Machine with a frequency range tailored to bass guitar and keyboards.

Inside the 14-gauge stainless steel chassis lies high-tech circuitry and premium quality components. 3 switchable frequency bands and 4 switchable filter bandwidths provide 12 distinct wah effects. Switchable Classic and Modern modes with an adjustable effect blend create even more possibilities and cure the annoying signal drop out common in other bass wahs. Continuous On mode lets you use the EQ-2 as a static filter to accentuate specific frequencies.

MSD's patented Automagic Revolution pressure-sensitive activator pad means no stomping to turn it on/off. Just step down and it activates, step off and it turns off.

Each EQ-2 is hand-built in Germany to designer Hardy Kurandt's specs and has a one-year parts and labor warranty.
