Boss BD-2W Blues Driver, 'Waza Craft' series. This is a proper all analog vintage-correct reissue of the old Japanese Blues Driver pedals, one of the most famous low-gain overdrives around. It's got the classic responsive tone you expect, and works well stacked with other drives etc or solo. Plus, it's a Boss so it's basically unbreakable. This is the second version, made in Japan with the silver screw.
