Based on the specifications of the original pedal developed by VOX in the '60s, the Vox V847A Wah-Wah offers guitarists the same legendary tone with the addition of AC power capability and a buffered input jack for preserving the unprocessed guitar tone when the pedal is not engaged. The pedal’s inductor has undergone a redesign to be closer in specification to the original VOX wah inductors, for improved dynamics and tone. Operates with a 9 volt battery or optional AC power supply. Also includes a vinyl carry bag.
