  • Price $ 229.99

Mythical Octave Fuzz Goes Galactic

Unicorn Blood II is a space-themed brother to the original Unicorn Blood. Now covered in cosmic glitter, with an even tighter fuzz and all the versatility that made its predecessor a collector's item.

This is a limited edition pedal, with only 420 pieces for sale. Ever. 

Launched on 4/20, this pedal celebrates creative freedom. Get high and riff all day!

 "Tastes better than ever."
- Brent Hinds, Mastodon

Trippy, hyper-versatile, a miracle worker

Unicorn Blood II is retro at heart, taking an iconic sound and beaming it straight into 2020 with modern features like True Bypass, Octatone, and additional EQ controls.

"It gets gnar!"
- Matt Pike, High on Fire

The first 250 pieces ship with a free bag of Unicorn Blood espresso blend by Dark Matter Coffee in a limited edition "Space Blood" bag.


Unicorn Blood’s design uses discrete transistors and germanium diodes for an authentic vintage fuzz tone. Each of the 420-piece limited series is hand-wired in KHDK's custom shop.

Unicorn Blood II Demo (Brent Hinds of Mastodon and Matt Pike of High on Fire)


1. [Volume] Controls the overall output volume of Unicorn Blood.

2. [Treble] At 12 o’clock, this control doesn’t modify your tone. Turned clockwise, it boosts your highs; counterclockwise, it cuts them. The frequency range is carefully chosen to offer you the best performance.

3. [Bass] At 12 o’clock, this control doesn’t modify your tone. Turned clockwise, it boosts the bottom end; counterclockwise it cuts the bass.

4. [Octatone] Emulates the TONE knob on your guitar by removing the unwanted shrill overtones high octaves can have, which is an issue for many players. You can pre-set it and it will activate in octave mode. The OCTAVE circuit works best with a neck pickup and the tone control set to low.

5. [Fuzz] Sets the amount of fuzz, from less gainy to fuzzier.

6. [Fat] Is designed to shift EQ curve of BASS and TREBLE controls. IT gives you a fatter tone with stronger singing mids. When FAT is set to OFF, it becomes more scooped.

7. [Boost] This switch offers a gain boost. Switch it On or Off according to your taste, pickups and mood.

8. [Sludge] This unique control adds loads of massive bottom end in the Pre-distortion section.

9. [Octave] This stompswitch activates the OCTAVE mode.
