Combining biting fuzz, multi-head tape-style delay, and vibrant modulation effects, the Keeley Dark Side Workstation pedal is tailor-made for psychedelic rock tone. The fuzz is based on a 1977 op-amp fuzz circuit, tweaked for maximum sustain and clarity. The multi-head tape delay effect offers 12 syncopated delay patterns, and the modulation section provides Flanger, Rotary Speaker, U-Vibe, and Phaser effects. A TS insert jack means you can add your own effects pedals between the Fuzz and Delay/Modulation sections, and a push button switch makes it easy to switch the order of your effects on the fly. Get even wilder with your effects by connecting an expression pedal (not included).
