The Red Witch Cybellium is a modulator pedal offering vibrato and phasing, made by the New Zealand pedal builder Red Witch Pedals. Red Witch describes it as "a gorgeous modulator offering vibrato and phasing"1. Under the hood, the maker says the Cybellium uses 6 transconductance operational amplifiers to generate its modulation1.
Controls
The Cybellium offers four controls, each shaping a different part of the modulation1:
| Control | What it does |
|---|---|
| Velocity | Speed of the modulation1 |
| Depth | Depth of the modulation1 |
| Wobular | A dial, not a switch, that blends between 4 and 6 stages of pitch shifting1 |
| Flavor | Tone character control1 |
The Wobular control is the pedal's distinguishing feature. Red Witch calls it "the magical Wobular control" and points out that it is "a dial that is, rather than a switch", so the number of pitch shifting stages can be set continuously between 4 and 6 rather than chosen from fixed positions1.
How it works
Under the hood, the Cybellium uses 6 transconductance operational amplifiers to generate its modulation1. Transconductance op-amps are a classic building block for voltage controlled modulation circuits, and Red Witch describes the result as the pedal's "glorious modulation"1.
Design and construction
Red Witch says the Cybellium is hand wired using premium Neutrik sockets, through hole components and ultra long life footswitches, and that every stage is hand assembled1. The maker's designer puts the pedal in the context of a long career: "I've poured twenty four years of designing guitar pedals into Cybellium's sound, look and feel"1.

Where it sits among vibrato pedals
The Cybellium combines vibrato and phasing in one pedal, which places it alongside other modulation pedals that blend vibe-style pitch modulation with phase shifting. Players comparing it with more conventional vibrato units can look at the Boss Waza Craft vibrato, the Diamond Vibrato or the TC Electronic Shaker, or browse the full range on the Vibrato Pedals page1.
Questions
What does the Wobular control do on the Red Witch Cybellium?
The Wobular control is a dial, rather than a switch, that lets you blend between 4 and 6 stages of pitch shifting. Because it is a continuous dial rather than a stepped selector, it sits between those two settings as well as at them, shaping how the Cybellium's pitch modulation is generated.
How many stages of pitch shifting does the Cybellium offer?
The Cybellium offers between 4 and 6 stages of pitch shifting, selected with the Wobular dial. The pedal generates its modulation using 6 transconductance operational amplifiers, according to Red Witch.
Is the Cybellium a limited edition?
Yes. Red Witch released the Cybellium as its 2025 end-of-year special batch pedal, limited to 69 one-of-one units. The maker describes it as its annual special release for that year.
Who designed the Red Witch Cybellium?
The Cybellium was designed by Red Witch, drawing on the maker's twenty four years of designing guitar pedals. Red Witch says it poured that experience into the pedal's sound, look and feel.
Is the Cybellium hand wired?
Yes. Red Witch says the Cybellium is hand wired using premium Neutrik sockets, through hole components and ultra long life footswitches, and that every stage is hand assembled.
Does Red Witch cover duty and shipping on the Cybellium?
Yes. Red Witch states it will cover the freight, duty and tariff charges for a Cybellium order, with items shipped by DHL international express tracked service.
