Selling my Beetronics Swarm Fuzz Harmonizer (Serial #390). Handbuilt in California, this unique analog fuzz-harmonizer transforms your guitar signal into square waves and lets you blend in nine different interval settings—ranging from heavy sub-octaves and upper octaves to wild, arpeggio-like modulated fuzz tones. Housed in Beetronics' signature custom brushed metal enclosure with intricate bee-themed detailing.

Condition & Details:

  • Excellent / near-mint cosmetic condition and 100% functional.
  • Clean bottom plate with all four original rubber feet intact (no Velcro ever applied).
  • No original box.
