The BOSS MD-500 Modulation Pedal has 12 different modes and 28 different modulation effects algorithms, each of which was created particularly for this pedal. Chorus, vibrato, flanger, phaser, tremolo, rotary, vintage vibe and ring mod are all included. There are also auto wah and touch wah effects, as well as BOSS originals like Slicer and Overtone. The option to program customized patterns, which was not available on the original SL-20 Slicer pedal, will be welcomed by Slicer lovers.

Effects in the MD-500 include many new Prime types developed with cutting-edge BOSS tech, plus authentic sonic recreations of vintage classics like the CE-1 Chorus Ensemble, Roland Dimension D, ‘70s script phaser, ‘80s tri-chorus and numerous others. With the ability to use two patches at once with A/B Simul mode, the MD-500 can likely cover all your mod needs with one convenient pedal. And by inserting drive pedals in the BOSS MD-500 flexible external loop, it’s easy to place modulation effects before, after or around the loop as needed for the very best sound.

Pig Power is a 9V 1000 mA power supply that can power up to 10 pedals at once (PP10DC 10 Spot Daisy Chain not included) and has a simple design that only requires one outlet.
