Featuring two distinct modes for vintage or modern gain structures, the Keeley El Rey Dorado overdrive pedal delivers the classic grind of the most iconic British Plexi amplifiers. In fact, Robert Keeley referenced his own JTM 45/100 stack to get that vivacious character just right. In Low Power mode, you'll find an old-school tone with more headroom and girth. In High Power mode, you'll find more compression, more harmonics, and a more defined tone. And because the Level control goes above unity, many guitarists at Sweetwater like using the Keeley El Rey Dorado as a boost pedal too.
