The V-Four’s four modes provide a full complement of tones and textures: Overdrive, Distortion, Metal, and the extremely high-gain and djent-ready Redline mode. Each mode is exceptionally responsive to picking dynamics and volume control changes. The V-Four also features Low, Mid, and High tone controls, plus controls for Gain and Level. The V-Four has a true-bypass Engage footswitch, and players can use the Select footswitch to scroll through each of the four modes. It’s powered by a 9-volt battery or external 9-volt power supply.
