The Wahcko mk.2 is an expressive wah pedal for guitar and bass, with six selectable frequency ranges and adjustable wah character to suit your instrument, rig and playing style.

A favourite in our line since 2008 used by the likes of Nile Rodgers, Mick Thomson, Mateus Asato and more, the Wahcko returns with a custom JAM inductor inspired by vintage TDK designs, a new internal Q control, selectable guitar and bass modes, and a newly designed custom rubber tread. The familiar six-position SWEEP and internal input-gain trimmer remain, while 9V battery operation makes its return. From the frequency range and intensity of the wah to the resistance and feel under your foot, the mk.2 gives you more ways to find a response that feels right.
