Works perfectly. The "Current Vibe" pedal by the domestic brand TRIAL, which recreates the vintage Uni-Vibe. It features a unique wobble and a liquid-smooth sound. Equipped with a "Current" control that simulates voltage fluctuations of the lamp, it produces a more realistic and organic sound. This is the perfect pedal for those seeking the psychedelic tones of the 60s and 70s. *Please understand that this is a used item.
