Bullseye DS-1 (Distortion) The DS1 is a very compact, “true bypass” distortion pedal with plenty of dynamic range and great harmonic overtones. An all-analog circuit, proprietary tone control, level and drive knobs ensure plenty of gain to suit any kind of musical style while maintaining an extremely open and clear sound that never gets muddy. We use proprietary circuits for gain and tone control that let you dial in an unlimited variety of great guitar tones.
