With a simple layout and natural clipping and feel, the Lightspeed has become one of the most relied on pedals in the game today.  Use it as a transparent boost to get your amp to that sweet spot or dial up the gain and let it rip.

From Greer:

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.
