The ZVEX Effects Vexter Box of Rock is a distortion pedal designed to emulate the sound of a cranked Marshall JTM45 amplifier. This 2-in-1 pedal features a boost and distortion channel, offering a wide range of tones from clean to high-gain. The distortion circuit delivers a punchy, clear sound with rich harmonics, while the boost circuit provides extra volume and headroom. Use the tone control for adjusting brightness to achieve a vintage-like sound, or crank it higher for a more contemporary tone. This "amp-in-a-pedal" offers the sounds of classic amp tones.
