Royal Flush is a dual channel overdrive with separate controls for each channel. The first channel is a low gain overdrive and is designed to create tube amp "early break-up" overdrive for rhythm tone with tone clarity. Second channel is a medium gain overdrive and is designed to capture creamy and rich sound of an amp-like distortion crunch. Both channels engaged emulate a more aggressive cranked tube amp sound with tons of sustain.
