Vox V846 VINTAGE Wah Pedal1967 is back the new wah pedal from the original creators Introduced by VOX in 1967, the Wah Wah pedal stemmed from the Midrange Boost feature of a VOX amp design and was initially marketed as a way to emulate the sound of a muted trumpet. However, it was soon revoiced for rock guitarists and rereleased as the V846, to keep up with the unintended but music changing use with electric guitar from renowned artists such as Jimi Hendrix and Eric Clapton.
