With 12 modulation modes derived from the flagship MD-500 pedal, the BOSS MD-200 modulation pedal is one of the most comprehensive mod pedals you'll find. And with ample options for external control, including footswitches, expression pedal, and MIDI I/O, it can turn your pedalboard into a veritable sonic playground. You can even use the insert function to patch in drive pedals and other effects for pre- and post-modulation processing. When you're looking for a specific modulation effect, you don't need to wonder if the BOSS MD-200 pedal has it — it does.
