http://www.musicgearguys.com http://www.tortugaeffects.com Part of the new Reptile Series, the Diamond Back is a great pedal to use with your already dirty sounding amp. Makes it tight and mighty right! I did this demo with a dirty signal from the Marshall head. Demoed with a Gibson SG Standard, and late 70's Marshall JMP 100 watt amplifier head into http://www.mojotone.com Mojo Tone 4x12 speaker cabinets, cocked rocked and loaded with Mojotone speakers. Microphones: Sennheiser e series e609, and http://www.royerlabs.com Royer Ribbon mic.
