The Dirty Haggard Koffein is a distortion/fuzz pedal from Dirty Haggard Audio, described by Delicious Audio as "a distortion/fuzz pedal with quirky function." It is a collaboration between Dirty Haggard Audio and Oak and Crow Coffee, and each pedal comes with a 12oz bag of the roaster's organic, fair-trade dark-roast coffee beans1.
What it does
Delicious Audio describes the Koffein as "a loud creature at heart, this pedal has a plenty of gain and output on tap, but sets itself apart for a rather quirky EQ"1. The circuit is built in three sections: an input gain stage, a 3-band EQ, and an output gain stage1. If you are comparing it with other dirt boxes, it sits in the overlap between distortion pedals and fuzz pedals.
Controls
The treble/feedback control in the output stage is the pedal's most unusual feature. Delicious Audio explains that it "adjusts high frequencies through this stage as you would expect, but when pushed, creates" a shrill feedback loop1. That makes it a tone control that doubles as a feedback tool at higher settings.
| Section | Control | What it does |
|---|---|---|
| Output gain stage | Treble/feedback | Adjusts high frequencies; when pushed, creates a shrill feedback loop1 |
The full 3-band EQ gives the player separate control over the low, mid and high content between the two gain stages, which is where the pedal's "quirky" character comes from1.
Noise gate
The Koffein includes a built-in noise gate, which Delicious Audio lists among the features that set the pedal apart alongside its gain on tap and its EQ section1. For a high-gain distortion/fuzz, a gate on board means less need for a separate noise gate pedal on the board.
