Bringing together a host of boutique features like an all-analog design, hand-wired circuitry for true vintage fidelity, and a unique Harmony knob on the side of the pedal which contours the EQ response, the BBE Ben-Wah takes the heart of a classic effect and puts it in a body suited for today's playing. Based on a 1967 Class A circuit built with a coveted Halo inductor and potentiometer, the Ben-Wah is a fast avenue to the wah tones of greats like Hendrix and Clapton.
