The Wahcko mk.2 is an expressive wah pedal for guitar and bass, offering six selectable frequency ranges and adjustable wah character to suit different instruments, rigs and playing styles.
In production since 2008 and used by players including Nile Rodgers, Mick Thomson and Mateus Asato, the mk.2 version features a custom JAM inductor inspired by vintage TDK designs, internal Q control, selectable guitar and bass modes, and a newly designed custom rubber tread. The familiar six-position SWEEP control and internal input-gain trimmer remain, while 9V battery operation has also returned.
Adjust the wah’s frequency range, intensity and underfoot resistance to tailor its response to your setup.
