The BOSS MD-500 is a powerful modulation pedal designed to cater to a vast array of modulation effects for musicians. With its advanced BOSS technology, the MD-500 provides 28 different modulation algorithms that include classics like the CE-1 Chorus Ensemble and historic effects such as the Roland Dimension D. Each effect offers extensive programming parameters, allowing artists to sculpt their sound precisely to their liking. Its class-leading audio quality is achieved through 32-bit AD/DA conversion and 96 kHz sampling rates, ensuring that the sound remains pristine, even beyond some top studio hardware. A/B Simul mode lets users activate two patches simultaneously, increasing its versatility, while its insert loop allows seamless integration of other pedals for more complex sound combinations.
