This is a redesigned version of Leqtique's popular Beryl model, based on the EVR concept. It can cover a wide range of distortion, from clean to overdrive to medium distortion, all in one pedal. From the official website: "The Beryl EVR has a two-stage gain stage, allowing for flexible control from smooth overdrive to edgy distortion." The EVR version has revised circuitry and component configuration, resulting in a well-defined sound and less low-end muddiness. It also responds well to picking nuances, making it an easy-to-use pedal for crunch to thick distortion. ・9V DC operation ・Operation confirmed ・Although there are almost no scratches, please understand that this is a used item.
