Boot-Leg Spiral SPL-1.0

Description

The Boot-Leg Spiral SPL-1.0 is a phaser pedal whose rate control determines the speed of the sweeping filter notches, while a depth knob adjusts how pronounced the phase-shifting effect is. A feedback or resonance control likely emphasizes the peaks and troughs of the sweep, making the effect more pronounced or vocal-like. The pedal's effect on the sound is a cyclical, whooshing modulation that colors the dry signal with moving comb-filter notches. It operates as a mono effect, with a standard input and output for guitar or other line-level signals. The Spiral's controls interact to shape the character of the phase sweep, from a subtle, slow swirl to a rapid, intense warble, depending on the settings of the rate and depth knobs.
