The Beetronics WhoctaHell is a low octave fuzz pedal with fully independent controls for the fuzz and the octave123. Beetronics describes the sound as an overdrive/fuzz summed up with a gnarly squared wave low octave, resembling an 8-bit bass synthesizer1. Where most octave fuzzes push the pitch up, the WhoctaHell drops it: a toggle switch selects an octave range of one or two low octaves below what you play456.

The pedal is monophonic, so it tracks one note at a time. Beetronics puts it plainly789:

"No, the Whoctahell is monophonic, delivering unpredictably glitchy square wave octaves in the best way possible."7

That glitchiness is part of the design rather than a flaw: single notes come out as a synthesized-sounding square wave an octave or two down, and anything beyond single lines gets wild789.

What it does to your sound

The WhoctaHell runs two things in parallel: an overdrive/fuzz voice and a squared-wave low octave. Beetronics describes the result as "a overdrive/fuzz summed up with a gnarly squared wave low octave, resembling a 8-bit bass synthesizer"1. In practice that means you can use it as a straight fuzz, as a sub-octave synth voice on its own, or as a thick, buzzy hybrid that reads like a bass synth under your guitar line.

The octave section has a range of one or two low octaves, selectable by a toggle switch1. Guitar World's review describes the original's selector as up for one octave down and down for two octaves down3. On bass, Beetronics confirms the pedal works, noting that "the second low octave get's pretty insane as you can imagine"7.

Controls and footswitches

The original WhoctaHell keeps its control set small. Delicious Audio's writeup lists the first-octave-down control as the Hell knob12, and Guitar Pedal X's coverage of the smaller Babee version names the full set: Whocta for one octave down, Hell for two octaves down, and Honey for fuzz level13.

ControlFunction
WhoctaOctave voice, one octave down13
HellOctave voice, two octaves down13
HoneyFuzz level13
Toggle switchSelects an octave range of one or two low octaves456

The v2 changes the layout: it features a fuzz and two low-octave voices with independent volume controls, allowing you to blend the mix of all three7.

Footswitching is where the WhoctaHell differs from a simple fuzz box. There are two footswitches, one for octave on/off and one for circuit bypass3. Guitar.com's review notes that bypass is handled by the second footswitch, marked by a red/blue LED11. Because the octave has its own bypass, you can leave the fuzz engaged and kick the octave in only when you want the sub voice14515.

Power, bypass and size

The pedal requires a 9VDC center negative power supply, which is not included1. No battery option appears in the maker's listings. The v2 draws 20mA, which Beetronics says means "pretty much any basic pedal power supply will bee fine"7.

Bypass is true bypass, confirmed by the maker for the v27 and described as true bypass circuitry in Pedal of the Day's review of the original10. Physically it is a mid-sized pedal: 5.5" x 4" x 2.75" including knobs and switches, in a 5.5" x 3.25" x 2" enclosure, weighing 1lbs / 0.5 kilos1.

History, the v2 and limited editions

The WhoctaHell has a particular place in Beetronics' story: it is the very first pedal the founder ever built, made for his own pedalboard while he was building pedals and modding circuits16. The company got its start when he sold a Whocta to a friend who kept asking for one, and before long his friends wanted one too16. Delicious Audio calls the pedal "a renewed take on the company's first pedal"12.

The Whoctahell v2 Low Octave Beeast is a reimagined take on that first pedal, which Beetronics describes as now more versatile, compact, and affordable8. Its release was capped at just 300 units total, including 40 Custom Shop and 20 Limited Edition units, leaving 240 standard units, most distributed through dealers7. Beetronics has said that if there is enough demand from its hive members, it may consider another run in a year or two, possibly with new features16. The v2 is sold out at the maker's store7.

Alongside the standard pedal, Beetronics has sold the WhoctaHell through a Custom Series of one-off painted finishes, a practice MusicRadar notes applies across its line, with standard and custom series models of each pedal17. Custom Series WhoctaHells include the Khao San, Cross Path, Icelandic, Prisma and White Crosses editions, plus a Black Limited Edition181920. These finishes are largely sold out at the maker's store201821.

Questions

Is the Beetronics Whoctahell monophonic?

Yes. Beetronics states the Whoctahell is monophonic, delivering what it calls unpredictably glitchy square wave octaves in the best way possible. Play one note at a time and the octave tracks; chords will not produce clean octave doubling.

Does the Whoctahell work on bass?

Yes. Asked directly whether the v2 can be used on bass, Beetronics answered that it can, and that the second low octave gets pretty insane. The maker also describes the pedal's overall character as resembling an 8-bit bass synthesizer.

Can you use the Whoctahell octave without the fuzz?

Yes. The overdrive/fuzz and octave sections work fully independently and can be used separately, and the octave has its own bypass footswitch. Beetronics adds that the magic really happens when you start blending the two.

What power supply does the Whoctahell need?

It requires a 9VDC center negative power supply, which is not included with the pedal. The v2 draws 20mA, which Beetronics says means pretty much any basic pedal power supply will be fine. No battery option is listed.

Is the Whoctahell true bypass?

Yes. Beetronics confirms the v2 is true bypass, and reviews of the original from guitar.com and Pedal of the Day also describe true bypass circuitry, with bypass handled by a second footswitch marked by a red/blue LED.
