The Greer Ghetto Stomp sounds like a lovely medley of old Supro, Valco and Gibson amps melded into one very pretty pedal. It's capable of getting those small, 5 watt amp about to explode sounds as well as some nice, tame, light overdrives. I really love the sound of this pedal with the tone and gain maxed. It just oozes attitude and is an absolute riff factory.
Cheers to Greer on this one, they did an amazing job.
