BWW-1 with four tone parameters switches enables you to match the tone to your needs. RANGE switch allows you to change the range of resonance frequencies. In HI position it is possible to use wah-wah effect without the influence on low-frequency harmonic sound. In turn LOW position enables higher influence on the low frequencies, what gives new possibilities of creating the tone. Q FACTOR switch let you adjust the deepness of the effect, especially the low part of the regulation band. TREBLE switch can boosts the volume of mid/high frequencies, what let you adjust the tone to higher part of resonance frequencies. The VOLUME switch adjust the level of output signal. BASS WOWEE-WAH features two switching modes: traditional (with the switch located in front of the pedal) and automatic mode (with the sensor of placing the leg on the pedal). Due to that, the switching OFF and ON of the wah-wah is far more faster and more comfortable what gives new creative capabilities. Photo element instead of potentiometer makes the using of wah-wah more easy and enlarges the effect reliability.
