The Effects Freak website says:
“The vintage Pearl Distortion DS-06 made in Japan (1980s). It has a six way selector for spectrum mode, this is like a parametric EQ for different tonal variations, different sonically than your basic tone knobs. A level to vary the amount of this EQ in the signal — then a separate out level and a control knob for the amount of distortion, very versatile pedal for its day and now for that matter.”
“Great distortion unit from the 80s. These Pearl pedals are top quality. The Spectrum part of the pedal has a six function rotary knob which provides for a variety of tones. Very similar to the Rat on one setting and like the Boss DS-1 on another.”
Includes new 9V battery. Can be mains adapter powered, 9V centre -ve.
Fully tested and working.
