The EHX Volume Pedal is part of their groun breaking Next Step Effects series. It boasts a direct & effect outputs with bypass level control, has zero moving parts and is built to be ultra-rugged. That means no pots, footswitches or any gears to break and it does not use a potentiometer, optics or magnetism to sweep the volume control. It delivers the accurate and very expressive control that you'd want out of a top end volume pedal. Essential for every pedalboard!
