JAM Pedals Wahcko Mk.2 Wah Pedal

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 has revisited the original design in detail, refining it further to expand its expressive range while giving players unprecedented control over its response.

At its heart is a custom JAM inductor inspired by the highly sought-after vintage TDK inductors found in classic 1960s Cry Baby and Vox wah circuits. Whether you are tailoring your frequency range with the familiar six-position SWEEP control or exploring the brand new internal adjustments, the mk.2 delivers vintage soul with modern versatility. Battery operation also makes a triumphant return, making this the ultimate wah pedal for purists and tone chasers alike.

Key Features

• Custom JAM Inductor: Inspired by classic 1960s vintage TDK inductors for authentic, vocal-like sweeps.
• Guitar or Bass Modes: For the first time, internal DIP switches allow the Wahcko to be configured for either guitar or bass, extending its expressive sweep to lower-register instruments.
• Tailored Sweep: The familiar six-position SWEEP rotary switch remains, allowing you to perfectly match the pedal’s frequency range to your rig.
• Enhanced Tone Shaping: The mk.2 introduces an internal Q trimmer for finer control over the character and intensity of the wah response, alongside the original's internal input-gain trimmer.
• Battery Powered: Battery operation makes a return for players who prefer a traditional power setup.
