The M68 Uni-Vibe Chorus/Vibrato is MXR's flagship chorus and vibrato pedal, delivering classic, premium tones in a compact package with a simple three-knob interface. Inside, a true bypass switching system maintains signal quality when the pedal is off. MXR M68 UNI-VIBE CHORUS/VIBRATO OVERVIEW The MXR Uni-Vibe Chorus/Vibrato delivers the same smooth tones players have loved since the late '60s, but has been updated to accommodate the needs of modern players. This pedal is housed in a rugged, full-size MXR case and features true bypass circuitry. The simple three-knob interface makes adjusting the effect easy. The Vibe switch lets you choose between Chorus mode, which provides a mix of clean and effected signal, and Vibrato mode, which provides only the effected signal. The Level control sets the volume of the effect, while the Speed ​​control sets the speed of the modulation and, finally, the Depth control adjusts the intensity.
