All DRAPsound presets, with the exception of Kemper Rigs, Tonex presets and Quad Cortex presets,  are sold inclusive of a specific IR for each individual sound. This is not only a single speaker/cab emulation IR: DRAPsound IRs are the synthesis of an entire emulation process that we use to create our exclusive "Real Tone": an extremely faithful replica of the real analog sound created with our collectors' amps and pedals.
