The Beetronics WhoctaHell Prisma is a low octave fuzz from Beetronics, the Brazilian maker known for bee-themed pedals like the OctaHive and Royal Jelly. Beetronics describes it as a Low Octave Fuzz with fully independent controls for the fuzz and the octave: an overdrive/fuzz voice summed with what the maker calls "a gnarly squared wave low octave, resembling a 8-bit bass synthesizer."1
The pedal was listed as sold out on Beetronics' product page as of 25 October 2026. It takes a 9VDC center negative supply, which is not included in the box.1
What it does to your sound
The Prisma builds two voices into one enclosure. The first is an overdrive/fuzz; the second is a low octave that tracks one or two octaves below your playing, selectable by a toggle switch. Beetronics' own description leans synth-like: the square-wave octave is meant to sit under your guitar like an 8-bit bass synthesizer, summed with the fuzz rather than replacing it.1
The two sides are not locked together. Beetronics says the od/fuzz and octave work fully independent and can be used separately, and that "the magic really happens when you start blending" the two. Each voice also has its own separate bypass switch, so you can bring the octave in and out without touching the fuzz.1
The Whoctahell family
The Prisma belongs to a line that goes back to Beetronics' first pedal. Related versions the maker has offered include the Whoctahell v2 Low Octave Beeast, the compact Babee Whoctahell, the Whoctahell Limited Beeast and the Whoctahell Cross Path. All share the same core idea: a fuzz or overdrive voice blended with a low octave.1

Questions
Can you use the octave on the Whoctahell Prisma without the fuzz?
Yes. Beetronics says the od/fuzz and octave work fully independent and can be used separately or blended together. Each side also has its own separate bypass switch, so you can run the octave alone, the fuzz alone, or both at once.
How many octaves down does the Whoctahell Prisma go?
The octave has a range of one or two low octaves, selectable by a toggle switch. Beetronics describes the octave as a gnarly square wave low octave that resembles an 8-bit bass synthesizer.
Does the Whoctahell Prisma come with a power supply?
No. Beetronics states the pedal does not include a power supply. It requires a 9VDC supply with a center negative connector, the standard format used by most pedalboard power supplies.
What power does the Whoctahell Prisma use?
The Whoctahell Prisma requires a 9VDC power supply with a center negative plug. Beetronics does not include a power supply with the pedal, so you will need to use your own 9V center negative supply.

Beetronics offers a 30-Day Hive Happiness Guarantee, with shipping not included. Email within 30 business days of receiving your order for an RMA form, then return the item within 7 days.
