Ultra Vibe
The Sweet Sound Ultra Vibe by Bob Sweet is a highly regarded, boutique analog modulation pedal designed to authentically replicate the legendary sounds of the original 1960s Unicord Uni-Vibe. Handcrafted in the United States, this pedal is celebrated for its warm, organic, and "chewy" character, famously used by icons like Jimi Hendrix, Robin Trower, and David Gilmour. It utilizes a sophisticated bulb-driven photocell circuit with custom-manufactured cells matched to much closer tolerances than vintage originals, ensuring a lush and consistent sweep. The Ultra Vibe features a simple three-knob interface for Volume, Intensity, and Speed, along with a toggle switch to select between Chorus and Vibrato modes. It includes a large speed knob for easy foot control and a rear jack for an external expression pedal. Built with high-quality components like glass epoxy plated boards and true bypass switching, it delivers studio-grade transparency and reliable performance for both guitarists and bassists.
