TC Electronic Viscous Vibe Settings Guide
The TC Electronic Viscous Vibe is a Uni-Vibe style photocell-based modulation pedal — reproducing the rotating speaker simulation and phase modulation of the original Shin-Ei Uni-Vibe. It covers both Vibrato mode (pure pitch modulation) and Chorus mode (mixed wet/dry phase modulation). Key for Hendrix, Robin Trower, and David Gilmour-style modulation effects.
Used by: Jimi Hendrix
The best TC Electronic Viscous Vibe settings start with: Speed at 4/10, Depth at 6/10, Level at 6/10, Mode at 1/10. Adjust from there based on your amp, guitar, and room volume. For Classic Rock / Psychedelic: Speed 4/10, Depth 7/10, Level 6/10, Mode 1/10.

Settings by Genre
Chorus mode at moderate Speed and high Depth — the Viscous Vibe in Chorus mode produces the signature Jimi Hendrix Uni-Vibe character on Machine Gun and Band of Gypsys recordings. Speed 4 and Depth 7 produces a noticeable but not overwhelming vibe effect. The photocell-based circuit produces the characteristic non-linear LFO shape that distinguishes Uni-Vibe from standard chorus.
Moderate Speed — Robin Trower and David Gilmour style vibe. The Viscous Vibe at Speed 5 produces the moderately fast vibe effect characteristic of Trower's bridge of sighs and Gilmour's early Floyd tones. Chorus mode keeps the dry signal present for note clarity in lead applications.
Vibrato mode at slow Speed — the pure pitch vibrato of the Uni-Vibe at low Speed creates a slow, deep pitch variation that simulates manual vibrato on a lap steel or pedal steel. Depth 7 in Vibrato mode produces prominent pitch variation. Useful for country and lap steel simulation on guitar.
Artist Settings
Documented settings used by professional guitarists on this unit.
Hendrix used the Shin-Ei Uni-Vibe primarily on live recordings in 1969–1970 — Band of Gypsys performances show the vibe effect on Machine Gun and Who Knows. He used Chorus mode at moderate Speed with full Depth to produce the swirling, pulsating character of his live tone in that period.
Tips & Common Mistakes
- The Viscous Vibe's photocell-based circuit responds to playing level — louder playing can slightly alter the modulation character in a musical way that digital LFO-based chorus pedals don't replicate. This makes it most effective at moderate to loud volume levels where the photocell interaction is most musical.

Speed: LFO rate — slow produces gentle swell; fast produces dramatic wobble. (Slow to Fast). Depth: Modulation depth — how pronounced the phase and pitch variation is. (Subtle to Deep). Level: Output level — the Uni-Vibe effect can slightly reduce perceived level. (Unity to Boost). Mode: Chorus (wet+dry) or Vibrato (wet only, pure pitch modulation). (Chorus to Vibrato)
