Since 2008, the Wahcko has been one of the defining pedals in the JAM pedals line, renowned for its expressive sweep, immediate feel, and dynamic response to the player, instrument, and amplifier.

With the Wahcko mk.2, Jam Pedals revisited the original design in detail, refining it further to expand its expressive range while giving players greater control over its response.

At its heart is a custom JAM inductor inspired by the vintage TDK inductors found in classic 1960s Cry Baby and Vox wah circuits.

The familiar six-position SWEEP control remains, allowing you to tailor the pedal's frequency range to your instrument, amplifier, and playing style. The original model's internal input-gain trimmer has also been retained, while the mk.2 introduces an internal Q trimmer for finer control over the character and intensity of the wah response. Battery operation also makes its return.

For the first time, internal DIP switches allow the Wahcko to be configured for either guitar or bass. This extends its expressive sweep to lower-register instruments while preserving the feel and musicality that have defined the Wahcko from the beginning.

Features:

- Six-position SWEEP rotary switch for selecting among six distinct frequency ranges
- Internal Q trimmer for adjusting the character and intensity of the wah response (default position~12:00)
- Internal input-gain trimmer (default position~12:00)
- Internal DIP switches for selecting guitar or bass mode
