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. Key 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.

Jam Pedals
JAM Pedals began in Athens in 2005 as guitarist Jannis Anastasakis’s workshop. The team still hand-builds, hand-paints and inspects its pedals in Athens, Greece, and offers a custom shop for point-to-point wiring and special builds. Its catalogue combines effects rooted in familiar analogue circuits with more individual designs. JustPedals listings include the Lucydreamer overdrive, Dyna-ssor compressor, Ripple phaser, Chill tremolo and bass-specific Lucydreamer. The distinctive finishes reflect the company’s craft process; the pedals themselves span drive, dynamics, modulation and other expressive sounds.

Wah & Filter Pedals
Wah effects sweep a resonant band-pass or related filter through the frequency spectrum, creating the vowel-like movement associated with the treadle. Envelope filters move automatically in response to picking level, while fixed and sequenced filters use other control sources. Sweep range, resonance, direction, sensitivity and input loading determine whether the response is vocal, percussive, smooth or sharply synthetic.
Tags
Analogue
The signal is shaped by continuously varying electronic circuitry rather than being converted into a digital effect algorithm. Component choice, operating voltage and circuit tolerances influence headroom, noise, clipping texture and the small variations in response between designs.
Bass
Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.
True Bypass
Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
Vocal
Designed for microphone-level signals and the frequency, dynamics and feedback behaviour of the human voice. Input gain, balanced connections, phantom power and pitch tracking may be provided so effects respond correctly before the signal reaches a mixer or PA.
