Very good to excellent condition, with original bag.

Cool sounds from a different type of wah. Video does a nice job of reviewing the sound.

The Boss PW-1 Rocker Wah is a vintage wah-wah pedal manufactured in Japan during the late 1970s and 1980s. It is notable for being Boss's first wah pedal and features a unique Hall-effect sensing system instead of a traditional mechanical potentiometer, which eliminates the scratchy noise often found in older wah pedals. Found Sound +2Key Specifications and FeaturesThe PW-1 is designed for high durability and is compatible with guitars, bass guitars, and keyboards.
