The SOS16  Speed of Light pack contains 40 captures of the Greer Lightspeed Organic Overdrive in each of the ToneX, NAM Standard and NAM Nano formats. (Full details above.)
 
Here's what Greer say about their pedal: 
 
'The Lightspeed Organic Overdrive is a very natural sounding overdrive. Why "organic"? Well, simply put, it's the clearest, most natural feeling, and best overdrive we've heard for the player looking for a natural drive tone. Blending with the tone of the guitar and amplifier, this pedal has rich harmonics and complex but smooth clipping. The Lightspeed Overdrive is sensitive to pick attack and has a different "feel" than other overdrives. The Lightspeed can be set to be "transparent," but can also drive your signal to the edge.'
