Built on the basis of the Greer Amps Lightspeed Organic Overdrive, the Southland Harmonic Overdrive takes the formula to the next logical step. This overdrive features more gain on tap, two stages of clipping, and a focused midrange. Its higher-gain capabilities result in a drive with an overall beefier voice with plenty of flexibility to fit in with other drives. Perfect for any player looking to push the proverbial overdriven envelope, Greer's expertise in overdrive shines.
