A wah-wah pedal with no rocker pot to wear out, it uses a proximity sensing radio transmitter so you can achieve super fast wah action and chewy sounds (pulling your foot quickly away), and it even has a Super Hard On built in so you can drive it to any volume you want.
Vexter Series pedals are lower priced, featuring silk-screened art. The parts inside Vexter pedals are identical to the hand painted models.
The probe circuit produces a small „bubble“ of RF energy at about a million cycles per second above the copper plate. As your foot or hand (or any wet or metallic object, for that matter) approaches the copper plate, the RF field is disturbed and the circuit reacts by increasing the brightness of an LED, which drives a photo resistive cell and controls the Z.Vex Wah circuit.
The volume level of the „drive“ knob… can be set so that when you kick on the Wah it’s doing its stuff at the right intensity. It goes from slightly lower than the normal guitar volume to completely bonkers when turned up all the way.
The RF field screwdriver adjustment on the bottom of the pedal, If turned in the direction of the arrow (usually to the left for that one), will make the probe circuit more sensitive and set the „bottom“ setting of the Wah higher and higher.
With the LED current control, you can usually leave this one at exactly halfway. That’s how the pedal is setup when shipped. If you think the Wah is too bright when your foot is all the way on it, just turn this control to the left to make it a little duller at the top end.
The unit works well with any kind of nine-volt battery. Normal, an Alkaline Battery will last quite a bit longer than a carbon-zinc one, but some people believe in the sound of the higher volt
