JAM Pedals Guitar & Bass Wahcko Wah mk.2

Product Description

The JAM Pedals Wahcko mk.2 Wah Pedal is an expressive wah for guitar and bass, offering six selectable frequency ranges and extensive adjustment over the sound and physical feel of the pedal.

At the heart of the Wahcko mk.2 is a custom JAM inductor inspired by vintage TDK designs found in classic 1960s Cry Baby and Vox wah circuits. The side-mounted six-position SWEEP control provides six distinct frequency ranges, allowing the response to be matched to different instruments, amplifiers and playing styles.

The mk.2 adds an internal Q trimmer for adjusting the character and intensity of the wah, alongside the retained input-gain trimmer. Internal DIP switches provide dedicated guitar and bass modes, extending the pedal's usefulness to lower-register instruments.

Rocker tension can also be adjusted using the included 4mm Allen key, allowing players to choose between lighter movement and a firmer response underfoot. True bypass, 9V DC or battery operation and a low 10mA current draw complete a flexible wah designed for expressive control across a wide range of rigs.
