Put 28 different modulation effects under your feet with the BOSS MD-500 pedal for electric guitar and bass. Both standard effects and previously unavailable original processes are available in this stompbox, making it suitable for lovers of classic chorus, trusty tremolo, and reliable rotaries, as well as aficionados of more esoteric effects, like Slicer (based on the BOSS SL-20) and Overtone (based on the BOSS MO-20).

The MD-500 provides its sound using 32-bit AD/DA conversion, 32-bit floating-point processing, and sampling rates of 96 kHz, in order to achieve a large and precise range of expression while maintaining utter transparency, free of unwanted digital artifacts. With a panoply of parameters in every effects type, you’ll find more than enough control for shaping your tone. In addition to dedicated panel knobs for effect depth and level, you’ll also be able to perform extensive editing via the LCD screen and quadrumvirate of push-buttons. A tap tempo/control footswitch offers more in the way of on-the-fly manipulation, while the A and B footswitches provide bank selection tools, as well as multiple instantiation options, such as A/B Simul (two effects patches at once in either series or parallel), or parallel to do different destinations via the stereo outputs on the real panel.

Speaking of I/O, the MD-500 gives you a bevy of possibilities, what with its dual inputs for stereo instruments, dual outputs, expression/control jack, and MIDI I/O. All in all, you’ll find 297 built-in patch memories in the unit itself, though you can also interface via USB with Editor/Librarian software on your computer for remote editing, storing your custom patches, and more. This pedal runs on four AA batteries, or by means of a power adapter, available separately.
