This pedal is one of the true classics. I'd put it in the same company as the Ibanez Tubescreamer TS-9, in terms of it's popularity. If you were to do a survey of guitarists pedal boards across the world, I'm guessing 90% of them would include either a TS-9 or Boss SD-1, or even both.
In terms of drive, the SD-1 and TS-9 occupy similar sonic territory, however, the SD-1 keeps going when the TS-9 has hit its peak. To my ears, the SD-1 is a little crunchier than the TS-9, and not quite as smooth, however that is not necessarily a bad thing. With some tweaking of the drive control, you can go from a nice little clean boost, right through to screaming overdrive.
Gear snobs may look down there noses at the Boss SD-1, but this bullet proof little yellow stomp box is one of the most useful and versatile overdrive pedals going around. There is a reason it has been a consistent seller for so many years, it's a solid performer and undoubtedly one of the 'best bang for buck' pedals on the market.
Famous guitarists known to have used the SD-1 at some point include John 5 (former guitarist with Marilyn Manson), Eddie Van Halen, Johnny Greenwood (Radiohead) and Steve Jackson (Belle and Sebastian). A fairly diverse bunch! Arguably one of the most recognised users of the Boss SD-1 Super Overdrive, up until his Dunlop sponsorship, was Zakk Wylde. The SD-1 has been a main stay in his rig for a very long time, pushing his JCM800 over the top.
The SD-1 is an awesome low budget alternative for any one looking for a boost/overdrive pedal without forking out for one of the 'boutique' options. It's simple and effective. You can pick one up brand new SD-1 for around $50US, however if you take a look on eBay you'll be able to find a second hand model for a lot less.
