The BOSS MD-500 is the most powerful and versatile modulation pedal BOSS have ever produced. Building on the success of the single pedal modulation range, the MD-500 takes modulation to a new level.
With 12 modes and 28 modulation types, the MD-500 offers a huge range of options. From slick chorus to lush vibrato, you have a whole world of options at your feet. With A/B simul mode you can run two patches simultaneously, enabling you to layer each patch even further for a full force modulation experience.
The MD-500 benefits from MIDI I/O for external midi control, while the USB connection allows you to fully utilise the free MD-500 editor and library software. There are 297 on-board patch memories which can be used for all your user presets while the easy to use controls make it simple to switch between patches.
It's a super comprehensive pedal that delivers studio quality in an easy to navigate pedal.
