Beetronics · pedal
The Beetronics Swarm Fuzz Harmonizer is an analog fuzz harmonizer from the Royal Series, handmade in Los Angeles. The SPECIES selector chooses from nine pitch intervals for the harmony voice, ranging from octaves to musical thirds including major third intervals. Queen and Drone knobs mix two harmony voices independently. Flight and Sting controls sweep, pulse, or detune the harmonized voices. The core fuzz is thick, buzzy, and gated, suppressing background noise when the instrument is not playing. 9V DC center-negative, approximately 7mA. Power supply not included. Pedal size roughly 5.5 x 4 x 2.75 inches. Reviewed by MusicRadar and guitar.com.
