I have found my Ernie Ball volume pedal to be reliable,transparent and built like a tank, but the sweep is a little too broad for me. I mostly use an old Roland volume pedal found at a yard sale for $4. I may pick a VS Visual Wah one of these days. The LED volume indicator would be a handy feature.
Every VS pedal I have is great. The Open Road and Dual Tap Delay never leave my pedalboard. The Liquid Chorus, Jeckyll & Hyde and Angry Fuzz all are on the regular rotation of my pedals. As an added bonus the V2 and V3 pedals now have a lifetime guarantee.
