Greetings from the Tweed Hut Music Store, Vacaville, CA. USA! Established 2002, We do a great job and will not let you down!

Particle™ is a granular delay / pitch shifting pedal. It chops your signal into small grains and then rearranges, shifts, and mangles it, using the techniques of granular synthesis in real time. Results range from radical pitch and delay modulation to shimmering repeats to time stretching, stutter, and glitch sounds.

Five delay and three pitch modes give intuitive control over random delays, bubbling textures, time stretching, and rhythmic glitches. Take a unique approach beyond conventional delay, pitch, flanging, and chorus sounds. Freeze notes with adjustable threshold for stutter, punch in, or drone-line effects. Lock multiple parameters to tap tempo or MIDI sync with independent note divisions for intricate rhythms. Access all parameters via MIDI, tablet, or “modeless” front-panel operation for full control over granular processing.

The Particle 2 is performance friendly, with controls spaced for real-time tweaking and designed so you can explore new sonic territory while remaining in control. Use the assignable expression pedal or DIY-friendly remote switch for hands-free control. The Particle 2 is pedalboard-friendly with all jacks on top. With full MIDI control, stereo input/output, and +8 dBu maximum input level, it is also at home in modular setups or the studio.
