The Sweet Sound Mojo Vibe takes all the rich, swirling sounds of the Ultra Vibe pedal and packs it into a more pedalboard-friendly enclosure. Get that authentic Uni-Vibe tone with on-the-fly control of the speed using your favorite passive expression or volume pedal. If you're looking for a brighter, more modern sound, an internal DIP switch puts an FET buffer into the signal path when the effect is engaged so that the sound of your guitar won't be choked off.
