50 captures in both ToneX v2 and NAM A2 formats of the Boss SD-1 Super OverDrive. For those using Genome, a Paradex model is also included. Details are in the thumbnail above.

First introduced in 1981, the Boss SD-1 has become one of the most enduring overdrive pedals in guitar history, equally at home delivering classic rock crunch or tightening up a heavily distorted amplifier. Derived from the earlier Boss OD-1, its distinctive asymmetrical clipping circuit produces a harmonically rich, slightly gritty overdrive with a pronounced midrange, controlled bass and plenty of bite. At higher drive settings, it delivers a crunchy, singing overdrive with plenty of sustain, but the SD-1 has also become a secret weapon for hard rock and metal guitarists. With the drive turned down and the level pushed up, it tightens the low end, sharpens pick attack and adds definition to palm-muted riffs, pushing an already driven amplifier harder without introducing excessive additional distortion. This capture pack includes an expanded range of lower-gain settings specifically for players looking to use the SD-1 as a boost in front of their favourite high-gain amp models.

The SD-1 has been used by an impressive range of guitarists, including Zakk Wylde (Ozzy Osbourne, Black Label Society), Steve Vai, Kirk Hammett (Metallica), Josh Homme (Queens of the Stone Age), Eddie Van Halen, John 5, Richie Sambora (Bon Jovi) and The Edge (U2), demonstrating its versatility across everything from blues and classic rock to modern metal.
