The Boss TW-1 Touch Wah, produced from 1978 to 1987, is a pioneering auto-wah/filter pedal that delivers a distinctive, funky tone characteristic of late '70s and '80s music. As one of Boss's earliest designs, the TW-1 features a streamlined interface with Sensitivity and Peak controls, along with a Drive switch to adjust boost levels. This pedal automatically applies a "wah-wah" effect based on the player's dynamics, enhancing expressive playability. Notably, the TW-1 underwent a name change during its production, transitioning from "Touch Wah" to "T Wah." Its robust construction ensures lasting performance, making it a valuable addition for both vintage enthusiasts and modern players seeking unique wah effects.
