2 Z.Vex Super Hard On pedals in one with master volume! Channel 1 has a single Level control; Channel 2 has a single Level control as well as the Master Volume, which controls output level with Channel 2 or both channels engaged.
The Box of Rock is Z.Vex Effects' first "distortion" pedal, highly specialized to simulate the "everything on 10" sound of a classic Marshall? JTM45 non-master-volume amplifier. Two effects in one box: a clean boost and a distortion circuit.
This is the perfect preamp pedal. The Crackle Okay volume knob is a negative-feedback control styled after classic 60's recording console inputs. Its name is its warning: the massive output from this pedal can be super hard on your amp, so tread lightly!
The main module contains a bank of eight Character switches, which adjust the fine and subtle nuances of tonality, harmonics and dynamics. A three-position Input switch gives you a choice of 3 pre-amp styles.
