PSK Wah Wah Pedal WP-100

Description

The PSK WP-100 Wah Wah Pedal is a passive-style wah effect that shapes the guitar signal with a band-pass filter whose center frequency is swept by the foot rocker. Rocking the pedal forward raises the filter's resonant peak, producing the classic "wah" vowel-like sweep, while rocking it back lowers the peak for a darker, muted tone. The treadle's position directly controls the filter sweep, and the pedal is designed to sit on the floor for foot operation. It uses a standard 1/4-inch input and output jack for mono connection in a signal chain, and it requires no battery or external power because the effect is passive, relying on the signal's own energy. The housing is a sturdy metal enclosure built to withstand stomping, with a non-slip surface on the rocker for foot grip. The internal potentiometer is the main control element, and its rotation is what changes the filter frequency as the treadle moves.
