The Coffee Grinder Fuzz is a fuzz pedal from Blue Dinosaur Electronics. Writing on Pedal of the Day in 2014, reviewer Mike B called it "a fuzz like no other," and described the circuit as "a distant relative of the ancient and mysterious Interfax Harmonic Percolator," rather than a clone of that circuit1. The Harmonic Percolator has long carried a reputation among fuzz players for odd, unpredictable character, and the Coffee Grinder takes a related approach rather than copying it outright1.
What it does
The pedal has a single Gain control that sets the amount of gain. With the Gain knob up full blast, Mike B found the Coffee Grinder "emits a warm, smooth, bold fuzz that's not tinny or harsh," and he described the pedal as shining when cranked, "for a unique and powerful full-on fuzz sound"1.
| Control | What it does |
|---|---|
| Gain | Sets the amount of gain; up full it produces a warm, smooth, bold fuzz, turned down it yields overdriven tones1 |
Turning the knobs down brings the pedal into milder territory: "You can get some nice overdriven tones from the Coffee Grinder by turning the knobs down a bit," Mike B wrote, though he judged the pedal at its best with the gain high1. Players looking for that lower-gain range may also want to compare it with dedicated overdrive pedals and distortion pedals.
"This is a fuzz like no other."
