Powered by advanced BOSS technology, the ultra-versatile MD-500 delivers nearly any type of modulation effect a musician could want, and then some. Included are 28 different algorithms with intensive programming parameters, offering a nearly limitless sound palette to create with. And with class-defying 32-bit AD/DA, 32-bit floating point processing, and 96 kHz sampling rate throughout, you’ll enjoy pristine sound quality that extends beyond the capabilities of the very best studio hardware.

• Studio-level sound with first-in-class 32-bit AD/DA, 32-bit floating point processing, and 96 kHz sampling rate
• 12 modes and 28 modulation types, all with deep editing parameters
• Classic mod effects and BOSS originals, newly enhanced with cutting-edge technology
• A/B Simul mode for using two patches at once, with your choice of series/parallel connection and mixed or split A/B output
• Insert Loop function allows you to use mod effects before, after, or around drive pedals
• Graphic LCD and intensive real-time control options
• 297 onboard patch memories and hands-on controls
• Selectable buffered-bypass or true-bypass operation
• MIDI I/O for interfacing with MIDI control devices
• USB-MIDI for connecting to the MD-500 Editor/Librarian or a DAW
• Runs on four AA-size batteries or PSA-series AC adapter

Twelve modes and 28 Mod effect types

The MD-500 includes 12 modes with 28 different mod effect algorithms, and every one of them has been newly developed specifically for this pedal. All the go-to standards are here: chorus, vibrato, flanger, phaser, tremolo, rotary, classic vibe, and ring mod. Auto wah and touch wah effects are on hand too, plus BOSS originals like Slicer and Overtone. Slicer fans will welcome the ability to program custom patterns, an additional feature to the original SL-20 Slicer pedal. And with the MD-500’s spot-on recreation of Roland’s Dimension D from the 1980s, you can add amazing width and depth with one of the most revered studio rack effects of all time.

Prime Tone

For the MD-500, standard effects like chorus, flanger, phaser, and others have been refreshed with BOSS’s advanced new Prime algorithms. Using ultra-fast, high-powered DSP and the latest technology, BOSS engineers have reimagined these essential effects for enhanced expression, extended range, and maximum transparency. With an array of adjustable parameters per type, you have a massive range of sound-shaping potential at your fingers. Some effects even have all-new parameters never seen in BOSS effects before, such as the Bell and Sweetness settings included in the Prime Chorus algorithm.

Advanced Interface, Intuitive Operations

The MD-500 is equipped with a large LCD that clearly shows the patch name and other vital performance information. It also makes it easy to view and adjust the unit’s deep editing parameters and advanced control features. With the grab-and-go panel knobs, you have top-level access to essential adjustments like depth and effect level, plus two parameter controls that change dynamically with the selected effect type. And via USB, you can connect with the free MD-500 Editor/Librarian on your computer for remote editing, patch backup, and more.

A/B Simul Mode and Insert Loop Function

A/B Simul mode further extends the MD-500’s versatility by letting you run two patches at once. A selectable series or parallel connection enables all sorts of tone-shaping possibilities, and you can even send each effect to its own separate output if you like. The MD-500 also features an external loop that lets you insert gain and drive pedals and set the ideal effect order on a per-patch basis. For example, you can place a phaser or classic vibe before a drive pedal in one patch, and a chorus or flanger after the drive in the next. And when you’re in A/B Simul mode, it’s even possible to position the loop between two different mod effects.
