Pre-owned in very good condition, original box and power supply not included.

The SD-2 is a fantastic sounding dual overdrive pedal with a crunch and lead mode. It has an external remote/footswitch input for dual channel switching.

From the manual 

"-Despite its compact size, this effect unit is capable of storing separate settings for backing as well as solo setups. This is possible thanks to the fact that it is equipped with two completely independent overdrive circuits. -A natural-sounding overdrive continues to be produced without any loss in its quality, even if you turn down the volume on your guitar. -You can simultaneously switch between Crunch/Lead and turn ON/OFF the effect after connecting an optionally available foot switch (such as the FS-5L) to the Remote jack. -A two-color LED makes it easy to tell at a glance whether Crunch or Lead is selected."
