JAM pedals Wahcko mk.2

The JAM Pedals Wahcko mk.2 is a wah-wah pedal for electric guitar and bass, built for players who want a vintage-voiced wah with modern flexibility and hands-on tone shaping.

At the core of the Wahcko mk.2 is a custom-made JAM coil, developed with reference to the TDK coils found in classic wah circuits from the 1960s. The result is an expressive, dynamic response that reacts to playing touch, instrument and amplifier, rather than a single fixed wah voice.

Where the original wah designs offered one frequency range, the Wahcko mk.2 adds a six-position SWEEP rotary switch, letting you choose the frequency range that suits the song. Internal trimmers go further, with a Q-control for adjusting the intensity and character of the sweep, and an input gain trim. A DIP switch inside the enclosure switches the circuit between guitar and bass modes, making this one pedal that works properly on either instrument rather than a guitar wah pressed into bass duty.

True bypass switching keeps your tone clean when the effect is off, and an LED shows when the wah is engaged. Each unit is handmade in Greece.
