Beetronics Swarm Fuzz Harmonizer Limited Edition Bambee

The Beetronics Swarm Fuzz Harmonizer Limited Edition Bambee is a limited edition version of Beetronics' Swarm Fuzz Harmonizer, an analog fuzz pedal that adds pitch-shifted harmonies to your guitar signal. Beetronics describes it as "an Analog Fuzz Harmonizer that sounds like a thousand killer bees coming to get you!"¹ It is hand made in California and, as of October 2026, it is sold out at the maker's store¹.

The pedal is a fuzz at heart, but the harmonizer side is what sets it apart from a standard fuzz box. Where a fuzz like Beetronics' own OctaHive or WhoctaHell pushes your signal into saturation, the Swarm rebuilds it as a square wave and then generates harmony intervals on top²¹³.

What the Swarm does: square-wave fuzz with nine harmony intervals

The Swarm's circuit works in two stages. First it turns your input signal into a square wave, the hard-edged waveform that gives fuzz its buzzy, synth-like character. Then it multiplies and divides the frequency of that square wave, producing nine possible harmonies spread across two different octaves, with modulation applied to the harmonies¹.

For a player, that means the pedal is not just distortion but a pitch effect: you can stack intervals above and below what you play, and the modulation makes those harmonies move rather than sit still. Beetronics says the range runs from vintage-inspired octave fuzz to buzzing synths and broken machine textures⁴. That puts it alongside octave and pitch pedals as much as fuzz, and it is a very different animal from Beetronics' simpler fuzzes like the Tuna Fuzz or the Royal Jelly OD/Fuzz.

The controls

The Bambee carries the same four controls as the standard Swarm line¹:

WORKER and MASTER handle the basic level balance, while SPECIES and STING are where the character lives: SPECIES picks the harmony interval, and STING determines whether the harmonies track your playing quickly or lag behind it, which is what creates the swarming, unsettled motion the pedal is named for¹.

Power

The Bambee requires a 9V DC power supply with a center negative plug, and Beetronics states plainly that a power supply is not included¹. Current draw is 7mA¹, which is low enough that it will run comfortably on nearly any isolated pedalboard supply or even a daisy chain with headroom to spare.

The Bambee and other limited editions

The Bambee is one of many limited edition finishes Beetronics has applied to the same Swarm circuit. The core pedal, the controls, the true bypass switching and the 9V DC center negative, 7mA power requirement are shared across the line, including the standard Swarm Fuzz Harmonizer Limited Edition, the Majin Bee⁵⁶⁷, Cream⁸, Pink Lemonade⁹ and The Blackbee Edition⁵⁶⁷. Beyond the named limited editions, Beetronics also builds individually numbered Custom Shop units, such as SW3115 and SW3577¹⁰⁷.

Several of these runs are listed as sold out, including the Majin Bee³.

Beetronics backs the pedal with what it calls a 30-Day Hive Happiness Guarantee, shipping not included¹. Returns work by email: you contact Beetronics within 30 business days of receiving your order for an RMA form, return the pedal within 7 days of receiving the RMA, and refunds are processed within 5 business days. A full refund requires the pedal to be in new condition in its original packaging; units showing wear or missing what Beetronics calls "bee-cessories" may instead receive a 15% restocking fee or store credit¹.
