Boss MD-500 Modulation Multi Effect Pedal

Powered by advanced BOSS technology, the ultra-versatile MD-500 delivers nearly any type of modulation effect a musician could want, and then some. Included are 28 different algorithms with intensive programming parameters, offering a nearly limitless sound palette to create with. And with class-defying 32-bit AD/DA, 32-bit floating point processing, and 96 kHz sampling rate throughout, you’ll enjoy pristine sound quality that extends beyond the capabilities of the very best studio hardware.

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 MD-500’s flexible external loop, it’s easy to place mod effects before, after, or around the loop as needed for the very best sound.
