This is a wah pedal that uses a pressure-sensitive sensor, activating only when stepped on, and allows for various settings adjustments. * No rubber feet. * The battery wire is broken. Please use AC power. The following is the manufacturer's description: The Wowee-wah series is a wah pedal developed using the technology of the highly acclaimed TBWP wah pad, which has been popular since its release. Like the TBWP, it uses a pressure-sensitive sensor to detect the weight of the foot for effect ON/OFF, instead of a mechanical or leaf spring switch, and features true bypass design. In addition, depending on your playing style, you can turn the effect ON/OFF with the built-in switch on the toe section, just like a traditional wah pedal, using the mini switch on the side of the pedal. Furthermore, various wah tone settings are possible with the mini switches on the top of the enclosure. Wowee-wah produces a great wah tone with any sound, clean, crunch, or heavy distortion, stimulating the player's imagination. It is designed to obtain a clear and deep wah tone without distortion even when connected to an instrument equipped with humbucking pickups in a clean tone amp setting. We have independently developed and adopted a circuit that reduces the sound thinning that is common with wah pedals, to obtain a thicker tone. ■ Controls and Switches Q-factor switch, Bass switch, Deep switch, Volume switch (For tone adjustment) BATT switch (Battery/Adapter power switching), ON/OFF mode switch (Footswitch/Pressure sensor switching) ■ Input, Output ■ Power supply connector: 9VDC, 10mA ■ Dimensions: 99(W) x 85(H) x 250(D)mm ■ Weight: 1.4kg
