Built with a three-knob design, a custom-designed high-gain circuit and warm mid-range response with a wide frequency spread, the Greer Relic Drive is one of the company's most flexible overdrives available. Designed on the screamer-type circuit with boutique attention to detail, the Relic Drive is already favorited by the likes of Patterson Hood of Drive-By Truckers and is perfect for attaining warm, aggressive overdrive.
