The Krakenheart Uni/Vibe is a Uni-Vibe style modulation pedal from Krozz Devices, covering both chorus and vibrato. It is the second evolution of the maker's original flagship pedal, retooled in February 2024 with six controls and a second footswitch. Guitar Pedal X describes its range as one "where you can go from really subtle flutters to full-flavoured deeply resonant chorusing and vibrato"1. For players, that places it among the more flexible takes on the Uni-Vibe format, sitting alongside the vibrato and phaser families it shares modulation territory with.
Controls and footswitches
The pedal keeps the core Uni-Vibe controls players know, and adds output shaping around them. Guitar Pedal X notes that "You can immediately pick out the core Uni-vibe controls - of Level, Depth, Rate (Pulse), and Dry-Wet Mix (central toggle"1.
| Control | What it does |
|---|---|
| Level | Sets output level, one of the core Uni-Vibe controls1 |
| Depth | Core Uni-Vibe control for modulation depth1 |
| Pulse (Rate) | Core Uni-Vibe rate control1 |
| Dry-Wet Mix | Central toggle, core Uni-Vibe control1 |
| Spectrum | Counterclockwise enhances mids, clockwise gives classic full-frequency response1 |
| Shadow | Frequency and wave symmetry control1 |
The pedal carries two footswitches:
- Bypass footswitch for turning the effect on and off1
- Hold / Ramp footswitch, on the left, which works with the Pulse control and the Ramp trim-pot for Rotary or Leslie-style rate changes1
The Ramp trim-pot and the expression port both sit on the right side of the pedal, with the expression port above the trim-pot1. Connecting an expression pedal there adds hands-free control on top of the Hold / Ramp footswitch.
Size, price and availability
The Krakenheart measures 120mm x 80mm x 70mm. Guitar Pedal X notes that "the enclosure is one of those narrow types that sits between 125B and 1590BB enclusers"1, a compact footprint for a pedal with six top-mounted controls and two footswitches.
It was available to order on the Krozz Devices webstore at $269 USD as of February 20241. In the UK, dealer Steve at FX Pedal Planet expected stock, likely at £2691.
What reviewers said
Guitar Pedal X's Stefan Karlsson, writing in February 2024, judged the pedal a standout in its field:
"Krozz Devices' Murilo Carozza has created a very special and supremely versatile take on that format here in it 2nd evol"1
The same review placed the pedal on the publication's acquisitions and wishlist, calling it a highly unique and expansively deeply textured Uni-Vibe1.

Questions
Who designed the Krozz Devices Krakenheart?
The Krakenheart was designed by Murilo Carozza of Krozz Devices. Guitar Pedal X credits Carozza with creating what the site called a very special and supremely versatile take on the Uni-Vibe format, retooled in its second evolution of the pedal, which was the maker's original flagship.
Does the Krakenheart have an expression pedal input?
Yes. The Krakenheart Uni/Vibe has an expression port located on the right side of the pedal, above the Ramp trim-pot. Connecting an expression pedal there lets a player control the effect by foot alongside the pedal's footswitches.
What does the Hold / Ramp footswitch do on the Krakenheart?
The Krakenheart has two footswitches: a Bypass footswitch and a Hold / Ramp footswitch. The left Hold / Ramp footswitch works with the Pulse control and the Ramp trim-pot to produce Rotary or Leslie-style rate changes, letting the player ramp the modulation speed up and down by foot.
How big is the Krakenheart Uni/Vibe?
The Krakenheart measures 120mm x 80mm x 70mm. Guitar Pedal X notes that the enclosure is one of the narrow types that sits between a 125B and a 1590BB enclosure, so it takes up relatively little pedalboard space for a pedal with six controls.
How much does the Krakenheart Uni/Vibe cost?
The Krakenheart Uni/Vibe was listed at $269 USD when it became available to order on the Krozz Devices webstore in February 2024. In the United Kingdom, dealer FX Pedal Planet expected stock at a likely price of £269.
