MD-500 Programmable Modulation

 Unleash a world of sonic possibilities with the Monster Mod Machine, the BOSS MD-500 modulation pedal. With 28 different algorithms and intensive programming parameters, you have an infinite sound palette at your disposal to create any effect you can imagine. Powered by advanced BOSS technology, the MD-500 is a class-defying modulation machine with 32-bit AD/DA and 96 kHz sampling rate for pristine sound quality that outperforms the best studio hardware.

The MD-500 includes many new Prime types, plus vintage recreations like the CE-1 Chorus Ensemble and Roland Dimension D. With the A/B Simul mode, you can use two patches at once, allowing for endless tonal possibilities. And with the external loop, you can insert drive pedals before, after, or around the loop for even more creative freedom.
