Boss DM-2W
In addition to an excellent reissue with much less noise, you get a new custom mode with more clarity and longer delays. Connecting an expression pedal further expands the capabilities of this unit.
Boss SD-1W
The Boss SD1W stacks up well against similarly priced pedals. If you were not a fan of the original, it is unlikely you will enjoy the Waza Craft version. However, if you were already a fan, but just want a little bit more from your SD-1, the SD-1W is an excellent choice!
