The SOS21 ’SD-1’ pack contains 40 captures of the Boss SD-1 in each of the ToneX, NAM Standard and NAM Nano formats. (Full details above.)
 
BOSS say that the ‘SD-1 produces the warm, smooth distortion of an overdriven tube amplifier while maintaining the subtle nuances of your picking technique. Unique asymmetric overdrive circuitry delivers a genuine overdrive effect for a classic guitar sound.’
 
Tickled by the toes of John Frusciante, Jack White, Dave Gilmour, Jimmy Page, Josh Homme, Jonny Greenwood, Eddie Van Halen, Kirk Hammett and many, many more!
