Seattle-based effects builder Seward Park Electric has released the Arabica, a new distortion/fuzz pedal that reimagines the legendary harmonic percolator circuit with expanded control and modern versatility—without losing the raw, confrontational character that made the original a cult favorite.

At its core, Arabica stays true to the snarling, harmonically rich DNA of the classic circuit. But where the original offered a single, uncompromising voice, Arabica opens the door to a far wider range of sounds. The pedal’s four-knob control set provides the ability to fine-tune your sound with much greater precision than the original harmonic percolator.
Arabica offers the following features:
- Tone knob: absent from the original design, this knob allows players to shape the pedal’s response with precision, from sharp, bright, and brittle clang reminiscent of Albini–style edge to warmer, fuller textures that push the circuit into entirely new territory while retaining its distinctive character.
- Space knob: a unique, presence-style control that injects a bit of “air” in the sound and is capable of enhancing octaves under the right conditions.
- Loud knob: controls the overall pedal volume.
- Push knob: adjusts the amount of drive hitting the silicon transistors and diodes for a range of clipping levels, from angular breakup to fuzzy distortion.
- 9-volt operation using standard external power supply, no battery compartment.
- True bypass foot switch.
Arabica excels at articulate grit, percussive attack, and complex overtones that cut through a mix, while giving players the ability to dial in just how aggressive or refined that character becomes. Whether you’re chasing familiar abrasive tones or exploring something new with a similar harmonic bite, Arabica delivers a nuanced evolution of a famously uncompromising effect.
Each Arabica pedal is designed and hand-built in Seattle, Washington using carefully selected components and a straightforward, purpose-driven, creative design philosophy that defines Seward Park Electric.
The Arabica carries a street price of $140 and can be purchased directly from Seward Park Electric at sewardparkelectric.bigcartel.com.
