OKKO FX Holy Grit Overdrive Fuzz Preamp

Gritty overdrive, low gain fuzz, vintage preamp – no matter how you call it, the Holy Grit combines the clarity and dynamic response of a great overdrive with the raw and complex texture of a vintage fuzz. The intuitive controls let you dial in anything from cleanish boost with a little grit to full-blown vintage „amp on 11“ sounds. Plug it into a clean or driven amp, stack with boosters, overdrives or fuzz pedals, Holy Grit will deliver – for guitar, bass, keys or whatever you want to spice up.

The circuit is based on the classic Fuzz Face/Tone Bender but heavily tweaked into something else. We’re using a set of matched low gain silicon transistors here (parts numbers may differ from unit to another), voiced between germanium warmth and silicon presence.

• FUZZ… well, you know. Level of distortion. Set low for boosting overdriven amps or dirt pedals and work your way up to see how far you can go.
• LEVEL, as expected, controls the output volume. Plenty of volume on tap, even with the Fuzz knob set to minimum.
• BASS is a pregain control so more bass = more fuzz. Play with it and you’ll find the perfect balance between tight/precise and bold/buzzy.
• TREBLE rolls off highs post gain at variable frequencies.
• BIAS TOGGLE selects one of three bias settings (individually set for each pedal): – UP = high headroom setting, least amount of fuzz and compression, tight and precise – MIDDLE = the „almost too low“ bias – dirty, buzzy, can get into velcro fuzz territory… fun! – DOWN = „the golden middle“
• BUFFER TOGGLE - UP = buffered mode. Don’t worry about the placement in your signal chain, just activate the HG’s special buffer and you’re set. Gives a little extra edge and presence in the mix compared to DOWN = unbuffered mode. If you prefer the classic way, just connect your guitar straight to the HG without the buffer. Slightly darker, more resonant tone, better cleanup with the guitar volume.
