From Boss:

With the 200 series, BOSS introduces a new generation of pedals that pack advanced sound and versatility into a streamlined size that saves space on your board. Grab-and-go controls and multi-function switches make operation easy and intuitive, while onboard memories allow you to store multiple setups for instant recall. All 200 series pedals feature premium audio quality with 32-bit AD/DA, 32-bit internal processing, and 96 kHz sampling rate, as well as support for additional control via external switches, an expression pedal, or MIDI.

The DD-200 Digital Delay brings together sounds and features inherited from the flagship DD-500 into an even smaller footprint. Twelve different modes offer an inspiring variety of delay colors from modern digital to classic analog, letting you dial up everything from basic echoes to rich ambient pads and everything in-between. There’s also a looper that’s always ready to use, plus a selectable carryover function for seamless transitions between memories.
