This is no ordinary volume pedal; Ernie Ball's MVP includes a whopping 20dB boost to up your gain for solos, while the treadle allows you to cut the volume back for rhythm playing.
It's a great idea, and the built-in boost works brilliantly, offering an organic way of wringing extra dirt from your amp, as well as full control over your gain levels.
You can use the MVP as a regular volume pedal, too, if you like, thanks to the provision of individual controls for the heel-down and toe-down settings.
At this price, the Most Valuable Pedal certainly lives up to its name, but plenty of players could find a use for this Ball in their signal chain.
