Featuring high-fidelity audio processing at 32-bit/96 kHz, the BOSS DD-500 Digital Delay Pedal has 12 delay modes that can evoke modeled analog ambience, clean digital repeats, and other delay types in between. While the delay processing is digital, it leaves your fundamental tone untouched as it passes through to the output, either as a true bypassed or buffered signal. Once your patches are set, they can be edited and manipulated in real time using the front-panel controls and footswitches, as well as separately available footswitches and expression pedals. With its built-in memory, the DD-500 can even function as a looper pedal.
