Some pedals are more fun than others. And on the fun spectrum, a new Vox wah is like getting a bike for Christmas. There’s gleaming chrome. It comes in a cool vinyl pouch that’s hipper than a stocking. Put the pedal on the floor and you feel the freedom of a marauding BMX delinquent off the leash, or a funk dandy cool-stepping through the hot New York City summertime. It’s musical motion. It’s one of the most stylish effects ever built. A good one will be among the coolest-sounding, too.
