Greer Amps have taken the Lightspeed overdrive and have made a few mods to give us the Southland Harmonic Overdrive.
- added a set of hard clippers after the first gain stage
- boosted the gain of the output to make up for the BAT41 hard clippers
- increase the drive pot value
Could try germanium diodes instead of the BATs, but it will probably sound about the same.
