COOLMUSIC A-ME01 is a pretty solid multi effect modulation pedal for electric guitar and bass. It contain 11 effects of Dyna Filter/ Wah/ Detune/ Chorus/ Vibrato/ Tremolo/ Flanger/ Phaser/ Rotary/ Ring.
This single pedal does most of the effects that you'd ever want. Adjustments are easy to make to each effect, and the backlighting for knobs and switch make it easy to find in poorly lit rooms.
DC 9V Center Nagetive Regular ( Not included), >300mA
