Boss DSD-2 Digital Sampler/Delay|Boss DSD-2 Digital Sampler/Delay is now part of! All the Boss pedals you love are still here, along with expert reviews of electric guitars, amps, and more.

The DSD-2 is a combined Digital Delay and Sampler pedal. The Delay has two modes, S and L. In S mode it is variable between 50ms and 200ms. In L mode it is variable between 200ms and 800ms. The technology is similar to the DD-2 and they are in fact sharing the same internal chip. When used as a sampler, two modes are available: Play and Rec/Play. In the play mode, a recorded sample sound can be recalled whenever the pedal is depressed or when an external trigger is fed to the DSD-2. In the Rec/Play mode, a new sound can be recorded while a previously recorded sound is being replayed. Recording and replay is archived simultaneously while the pedal is depressed. The sampling time is limited to a maximum of 0.8 seconds.
