The Keeley Dark Side is a multi-effect workstation featuring three different effects that make up the core of a certain player of a certain black Stratocasters tone. The Dark Side has a fuzz style circuit based on a 1977 op-amp design, going into the Delay and Modulation side. You can select between a multi-head tape delay effect or between a combination of 4 different modulation sounds. The Dark Side has many subtle filters to get the tape delay setting to have the feel and warmth of the original machines, yet gives you range of control to have modern features like expression pedal control for the number of repeats. You can use it for creating a feedback oscillation delay. Extremely subtle modulations in the delay make it very musical. The next atom in this workstation is the modulation effect. There are four parts to this effect. You can blend between the “Electric Lady” Flanger and a Les-Rotary cabinet, creating new sounds. You can find that perfect blend between a vintage sounding opto-coupler based U-Vibe and the little orange phaser.
