Product Description
The JAM Pedals Wahcko Wah Mk.2 is a premium, fully analogue wah designed to deliver classic 1960s style vocal sweep with modern flexibility and control. Centred around a custom JAM inductor inspired by legendary vintage TDK units, it offers six distinct sweep ranges, internal voicing tweaks and selectable guitar or bass operation, making it a serious tone tool for players who want their wah to feel tailored rather than generic.
From subtle, expressive filter movements to wild, quacking funk tones, the Wahcko Mk.2 is built to sit perfectly with your instrument, amp and playing style. True bypass switching keeps your core sound intact when the pedal is off, while the low current draw and 9V operation make it easy to drop straight onto your existing board.
Vintage Inspired Core Tone
At the heart of the Wahcko Mk.2 is JAM Pedals own custom inductor, modelled after the revered TDK inductors used in classic 1960s Cry Baby and Vox circuits. This gives the pedal that familiar, vocal character and organic sweep that players associate with the golden era of wah, making it ideal for everything from blues and rock to fusion and funk.
Six Distinct Sweep Ranges
The six position rotary SWEEP control lets you choose from six carefully tuned frequency ranges. Whether you prefer a darker, throatier wah for chunky rhythm work or a brighter, cutting sweep for lead lines, you can quickly dial in a response that complements your guitar or bass, your amp and the role you play in the mix.
Deep Internal Voicing Control
Inside the Wahcko Mk.2 you will find an internal Q trimmer and an input gain trimmer, giving you precise control over how the pedal behaves. Adjust the Q to fine tune the sharpness and intensity of the wah peak, then set the input gain to match your pickups and playing dynamics. Internal DIP switches also let you configure the circuit specifically for guitar or bass, so the pedal always feels optimised rather than one size fits all.
Player Focused Feel and Integration
Beyond tone shaping, the Wahcko Mk.2 is designed to feel great underfoot and integrate smoothly into your rig. Adjustable rocker tension allows you to set the treadle resistance exactly how you like it, from loose and fluid to firm and precise. True bypass switching keeps your signal path clean when the pedal is disengaged, while the 9V DC or battery power options and low 10mA current draw make it straightforward to power on almost any board.
Features
- Custom Vintage Inspired Inductor - The custom JAM inductor, inspired by vintage TDK units from classic 1960s wahs, delivers an authentic, vocal sweep that feels instantly familiar under your feet and sits naturally in a band mix.
- Six Position Sweep Control - A six position rotary SWEEP switch provides six distinct frequency ranges, so you can tailor the wah response to your instrument, amp and musical style rather than being stuck with a single fixed voice.
- Comprehensive Internal Voicing Options - Internal Q and input gain trimmers, along with guitar and bass DIP switch modes, let you fine tune the character, intensity and overall response of the Wahcko Mk.2 to perfectly match your pickups and playing dynamics.
- True Bypass and Player Tuned Feel - True bypass switching keeps your tone pristine when the pedal is off, while adjustable rocker tension lets you customise the physical feel of the treadle for confident, expressive control on stage or in the studio.
