INTRODUCTION
The Runoffgroove Tri-Vibe is a vibrato & phaser circuit that is a great deal simpler than the comparable
vintage circuits. Unlike most vibrato implementations, no BBDs are used, and instead the Tri-Vibe's
topography is much more similar to a phaser using OTAs, but with an LFO that has been optimized for
the vibrato effect.
The result is true pitch vibrato-not just the deep phasing that is often called vibrato in circuits like the
Univibe. However, by mixing the dry signal back in via a toggle switch, the Tri-Vibe can achieve more
traditional phaser tones similar to two-stage phasers such as the Phase 45.
The Aion FX version of the Tri-Vibe is a direct adaptation of the original Runoffgroove circuit with no
modifications, just a little bit of additional power filtering.
USAGE
The Tri-Vibe has the following controls:
• Rate controls the speed of the LFO.
• Depth sets the depth of the LFO.
• Mode is a toggle switch that goes between vibrato (center), "whirl" (phaser) and "swirl" (somewhere
between the two).
