2021-08-05 Update : Here's our DerrylV artist edition of the GrindR. Handpicked parts by Derryl himself to make our GrindR the most badass looking ever. Black Footswitch, black laser etched design, green led, all black knobs.
Wanna boost ? 20db of clean boost, with a bypassable (left switch) preamp (bass and treble control). Right toggle let you switch between the original “Grind” or the “33” EQ.
This, is a three in one, including the old school popular Integrated Preamp, switchable with the left toggle.
In "P" (Preamp) position, Bass and Treble became active. In "B" (Bypass) mode, you only have Level and EQ type control.
Power consumption : 21mA
Voltage : 9Vdc ONLY, center negative. Anything over 9V will blow the pedal.
