The Particle is a granular delay/pitch shifting pedal that offers some effects previously available only in DAW plug-ins. It chops the signal into small grains and then modulates the sound, using the techniques of granular synthesis in real time. Results range from radical pitch and delay modulation to shimmering repeats to stutter/glitch sounds.
Sounds awesome. Just recently found this site, but I read it religiously now.
I have had a Particle since a little before Christmas. Extremely cool pedal. You can get some really strange/interesting textures from it. Very cool!
