The Gray Channel™ is a real “twofer” of an overdrive. It is based around a classic hard-clipping gray box overdrive (subtle hint, huh), one of my all-time favorites. Coincidentally, this is the very same pedal that got me started building pedals and launched EQD. It is two channels of a simple hard clipping overdrive that leaves the character of the guitar and amp intact. The Gray Channel retains the classic warm overdrive sound and expands upon it with several clipping options and bigger bass response.

With more and more drive pedals moving onto already crowded pedal boards, having the Gray Channel dual overdrive is like, totally crucial for sonic growth and sustain. Join the fight to stop pedal board overcrowding, because before we can overdrive tomorrow, we must first drive today... or something.

Green Channel Controls
Gain: Adjusts the drive. Dirtier clockwise, cleaner counterclockwise.
Green: Sets the output level when the green LED is lit.
Toggle: Si - Silicon clipping, N - No clipping, Ge - Germanium clipping.
Red Channel Controls
Gain: Adjusts the drive. Dirtier clockwise, cleaner counterclockwise.
Red: Sets the output level when the red LED is lit.
Toggle: LED - LED clipping, N - No clipping, FET - Mosfet clipping.
Footswitches
Channel Switch: Selects between Red and Green channels.
Activate Switch: Turns the effect on and off.
Each channel has 3 clipping modes. The Green channel offers Si (Silicon clipping diodes), Ge (Germanium clipping diodes), and N (no clipping diodes). The Si mode is bright, loud, and fuzzy with a natural tube-like breakup. Ge mode is a little looser, with more low end and warmth, but slightly less output. N mode acts as a clean boost until you reach roughly 1 o’clock on the gain, at which point it begins to saturate the op-amp into a biting, loud distortion.

The Red channel. This channel has LED (LED clipping diodes), FET (Mosfet clipping diodes), and N (no clipping diodes) modes. LED mode is the loudest, cleanest, and most touch-sensitive with the least compression. FET mode is the most compressed with a tighter crunch, offering the biggest “hesher” of the group. Finally, N mode is the same clean-to-crazy-loud op-amp distortion setup as the Green channel. With a few switch clicks, you can go from your bypassed tone to warm breakup to over-the-top gnarly grind and every combination in between.
