The way this works is genius, no switch to clamp onto it simply starts as soon as you press down on it meaning you dont need to start your wah at the end of its sound envelope but at the begining where it will sound coolest. It also switches off when not pressed so it conserves power/battery. Its sound isnt adjustable like later versions but honestly the contours are very tastefully done. I put this at the begining of my pedal board right after a tuner as it sounds best before the distortion rather than after it.
no switch......buffer ....electro-optical..... short coarse .... but can't stay in place without the help of your foot because it returns back completely to ZERO point ... like a old wah to close or open frequencies ... automatically switch from in use status to bypass when foot step out .. built like a tank (don't forget to use 9v 300 mA DC help to get any annoying noise !!!
