Description

The Mad Professor Snow White Auto Wah PCB Pedal is In stock available now for fast UK delivery online for £199.99 + Delivery. This excellent piece of kit is manufactured by Mad Professor and in New condition and comes with a great warranty.

The SNOW WHITE AUTOWAH (SWAW) circuit is based on a 1991 BJF rack mount remote wah circuit and is tuned like a real wah.

The circuit was redesigned with envelope controls and built into small size pedal.

It has very fast tracking and accuracy rarely found on auto wahs/ envelope filters. With the four knobs you can have total control of the effect.

SWAW works both with guitar and bass and you can fine-tune the pedal to suit your instru-ment, your playing style and your taste of tone.

The pedal has a unique decay control for the filter frequency fall speed. You can set it to be fast for wah effects on every note, or slower for a more traditional auto wah sound.

Controls

  • SENSITIVITY: Sets the filter trigger level, tune this carefully to fit your guitar/bass output and your playing touch. You can further change the sensitivity from your guitar volume knob while playing.
  • BIAS: Controls the filter resonance frequency. When Sensitivity is turned fully off the Bias can be used as a sweepable filter.
  • RESONANCE: Controls the sharpness or Q-factor of the filter.
  • DECAY: Controls how fast the filter frequency falls back to resting point (that is set with the Bias control). This can be set fast (CW) so you get the wah effect on every note or slow for a more traditional auto wah sound.
  • PLAYING: Please take time to get used to the controls and as this is a voltage control filter it will react to your playing touch. The envelope control circuit is carefully designed to follow the dynamics of guitar/bass and it might take some time to master the Auto Wah playing technics. Try also adjusting guitar volume between 8 and 10 to further expand use.

Guitar Effects Pedals

Guitar pedals are essential tools for shaping your sound, offering everything from subtle tone enhancements to wild, expressive sonic textures. Whether you’re after the grit of overdrive, the shimmer of chorus, the depth of reverb, or the psychedelic swirl of delay and modulation, pedals allow players to personalise their tone and push creative boundaries. Each stomp box adds its own flavour, and when combined, they become a powerful extension of the player’s voice. From vintage classics to cutting-edge innovations, guitar pedals are where the magic happens—turning a great tone into something unforgettable.

Guitar FX

Guitar FX (effects) refer to the wide range of pedals and processors that shape and manipulate a guitar’s signal to create different sounds. From classic distortion and overdrive to reverb, delay, modulation, and pitch-shifting, effects are at the heart of a guitarist’s creative toolkit. Whether analogue or digital, stompbox or multi-effects unit, Guitar FX allow players to express mood, texture, and dynamics in unique ways. Used thoughtfully, they can transform a simple riff into something atmospheric, aggressive, or entirely otherworldly.

pedal

A pedal is a compact device that guitarists use to alter their instrument’s sound by shaping effects such as distortion, delay, reverb, and modulation. Typically housed in a rugged enclosure and controlled by footswitches, pedals are designed to be placed on the floor for hands-free operation during playing. They can be analogue or digital, true bypass or buffered, and come in countless varieties to suit different styles and preferences. Pedals are essential tools for creating signature tones and adding colour and texture to a guitarist’s sound.

PRS (Paul Reed Smith) is renowned for its high-end electric guitars and amplifiers, but the company also produces a range of premium guitar effects pedals. PRS pedals are known for their meticulous craftsmanship, robust build quality, and superior tonal characteristics, reflecting the same attention to detail and innovation that the brand brings to its guitars. The company’s effects lineup includes overdrive, distortion, and modulation pedals, designed to enhance and complement the natural sound of PRS guitars.

Among the most popular PRS pedals are the Horsemeat Transparent Overdrive, Wind Through the Trees Dual Analog Flanger, and Mary Cries Optical Compressor. The Horsemeat Transparent Overdrive is praised for its clear, articulate overdrive that preserves the guitar’s natural tone while adding a touch of warmth and grit. The Wind Through the Trees Dual Analog Flanger stands out for its rich, lush flanging effects with two independent flangers that create complex, swirling sounds. The Mary Cries Optical Compressor is favoured for its smooth, transparent compression that enhances sustain and dynamics without colouring the tone. These pedals have gained acclaim for their high-quality sound, innovative features, and the reliable performance that PRS is known for.
