Jam Pedals Wahcko Bass Wah Pedal

The JAM Pedals Wahcko Bass Wah is a boutique-grade wah-wah designed specifically to unlock the full expressive potential of bass guitars. Rich, vocal-like, and deeply musical, it’s an ideal match for players wanting fluid controls and tonal nuance in every octave.

Its core is built around the sought-after RED Fasel inductor, delivering that classic medium-bodied sweep sparkle with punch and clarity. Inside, carbon-comp resistors and a bufferless proprietary circuit maintain full dynamics and seamless interaction—even when placed before fuzzes or vintage effects that are notoriously touch-sensitive.

A standout feature is the 6-position rotary switch, which lets you tailor the frequency sweep to match anything from tight growl to open vowel-like vocal tones. An internal gain trimmer helps you set the perfect input level for different pickups, while a mini LED gives clear status feedback on stage.

Despite its boutique build, the Wahcko Bass remains practical: powered by 9V DC (centre-negative), draws low current (under 30 mA when active), and can be battery or adapter powered. It features true bypass switching, ensures pure tone when disengaged, and includes replaceable rubber tread for custom feel.

Hand-built in Greece and awarded by pros for its flexibility and expressiveness, the Wahcko Bass is a standout from JAM Pedals’ lineup and a staple for players chasing vowel-like accentuation, growl, or vintage scoop that responds fluidly to your dynamics.
