The El Rey covers a lot of classic British amp tones by featuring two gain modes with the Power Toggle. With the Power Toggle switch you have control over the compression and harmonics. Low Power mode is louder, has more girth, and has fewer harmonics for a more old-school tone. The High Power mode has more compression, more harmonics, and a tighter, more defined tone. Old-school crunch in Low Power mode, super lead tones in the High Power mode.
