Even-order Overdrive Harmonics for Superb Versatility

From crisp, clean sounds to filthy, ragged fuzz, the Catalinbread Karma Suture Silicon Overdrive/Distortion pedal gives you everything you need to take your guitar tone over the top. Based on the now-rare Harmonic Percolator pedal’s tone circuit, the Karma Suture Silicon features the proven pairing of one silicon NPN and one silicon PNP transistor (plus two silicon diodes), generating an asymmetrical clipping response and even-order harmonics that slice through the mix and sound great regardless of the notes played. To expand on the potential of the Harmonic Percolator, Catalinbread gave the Karma Suture both Diodes and Density controls (and renamed the original’s “Harmonics” and “Balance” knobs as “Input” and “Output”). Together, the four controls open up worlds of possibilities, letting the Karma Suture function as a gnarly fuzz pedal, a musical boost, a go-to overdrive, or a life-giving companion to the other effects pedals on your board.

More than a dirt box

The Karma Suture Silicon makes a great distortion pedal, but with purposeful manipulation, it can become so much more. The silicon transistors immediately attack with an aggressive tone that will stand out in the loudest mix. Use the Density control to hit the sweet spot at one end of the range between fuzz and overdrive (or somewhere in between), and manipulate the Diodes knob to set the clipping circuit’s threshold anywhere from zero to full-on beast mode. Input can be set low for a lively, controllable boost — or way up to load up the harmonic generator, resulting in major fuzz bursts. The Output is your volume control, offering plenty of power for any musical environment. Crank it, and in Catalinbread’s words, your guitar’s harmonics will “bloom and bloom, turning your power chord into a tantric event!”

Gear that makes you want to play

The self-avowed gearheads at Catalinbread focus on making musical devices that they want to use themselves — “gear that gets us excited and inspires us to play.” The result of that authentic focus and unwavering integrity is the type of innovation that isn’t market-driven; Catalinbread creates its own market for products players love, whether overdrive, delay/reverb, fuzz/distortion, or tremolo/modulation pedals. The Karma Suture Silicon is a great example of Catalinbread’s exciting, inspiring innovation.
