DSD-3 Digital Sampler/Delay

The DSD-3 is identical to the DSD-2 apart from the model designation. The DSD-3 was however released with a much lower price than its predecessor. This was made possible because of a drop in semiconductor prices at the time. As a result Boss decided to release it as a new version rather than dropping the price of the existing DSD-2.
