Sonuus Wahoo





The Wahoo™ is NOT an ordinary Wah pedal!

Instead, the Wahoo™ is a dual analogue filter stomp box where each filter can be configured as low-pass or band-pass and operate independently in wah pedal, envelope, LFO, and unique pitch-tracking modes. The warm-sounding fully analogue signal path is digitally controlled for precision, configurability and adaptability. 100 factory presets let you explore some of its possibilities, while 100 user presets give you ample space to store your own creations.

Whether you want to recreate the character of vintage wah/filter pedals or break new sonic barriers, the Wahoo™ can do it for you.

Warm Organic Tone

By using an analogue filter topology based on vintage synthesizer filters, the Wahoo™ generates a warm tone with an organic feel. Something that’s not possible using digital effects.

A drive control lets you gently overdrive the filters to increase the warmth or crank it up to get fuzz-wah tones.



Packed with innovations, the Wahoo™ lets you invent new sounds.



  • Warm organic analogue tone.
  • Dual-filter design.
  • Digitally controlled with 100 expertly-crafted factory presets and 100 user presets.
  • Patent-pending pedal sensor that will never wear out.
  • Transparent-True-Bypass switching.
  • Wah pedal, envelope, LFO and Pitch-tracking filter modes.
  • Future-proof upgradeable firmware.
  • 9 VDC, 4xAA batteries, USB-powered.



The filters have a wide frequency range of 10 Hz – 4 kHz, and wide resonance range from flat to self-oscillation. Moreover, resonance is not fixed, but can be varied dynamically so it can track the cutoff frequency to further expand your creative possibilities. Combining this with drive, response curves and variable envelope filter attack/decay allows you to replicate the sonic character of many vintage and modern wah/filter pedals.



It’s simple to tweak settings on the carefully designed control panel. Once you have created what you want, you can save it to one of 100 internal presets.



As well as being ideal at home or in the studio, Wahoo™ has special features that make it perfect on stage. The sturdy, lightweight aluminium chassis, paired with modern robust electronic design ensures that the Wahoo™ will stand up to the demands of the toughest gigs. The large bright display is readable outdoors but can also be dimmed when required in low-light environments.

A lock switch ensures that settings cannot be changed accidentally in the heat of a performance, but still allows you to select which preset to use. Foot-operated selection of presets lets you access what you need with minimum hassle.

Powered by 9VDC, 4xAA batteries or USB, and with modern-yet-retro styling, you can be sure Wahoo™ will fit into your rig.


Unique patent-pending pedal sensor

Most wah pedals operate using a potentiometer (a pot) which wears out quickly resulting in the effect becoming scratchy. These also have mechanical couplings which limit fine control and let dirt inside the unit, so compromising reliability.

Some other wah pedals use optical methods which are susceptible to dirt, and these also have mechanical couplings.

For the Wahoo™, we designed a brand new type of position sensor that allows super-fine precision control with no mechanical couplings. As a result, the pedal control on the Wahoo™ won’t get scratchy and will never wear out!



True-bypass means that the effect is completely switched out of your signal chain when bypassed to preserve the integrity of your guitar/bass signal. This is typically done by mechanical switches but these cause clicks or pops when switching.

For the Wahoo™, we designed a silent-switching true-bypass circuit so you get the benefits of true-bypass without the associated switching noise. What’s more: if the power to Wahoo™ is interrupted, the unit will automatically switch back to the bypassed state so you don’t lose your signal.

Computer Connection

A USB connection lets you connect Wahoo™ to a computer where the Desktop Editor Software allows visual preset editing and manipulation. Presets can also be save to, and loaded from, files for exchange with other Wahoo users.

USB-MIDI can be used to sync internal LFOs and to automate the filter parameters. The expression pedal also sends MIDI controller messages to drive software instruments and effects.


Future-Proof (Upgradeable Firmware)

To support new features and to make it futureproof, the firmware (internal software) of the Wahoo™ can be upgraded. This means you can invest with confidence in the Wahoo™.



Desktop Editor Software

The digital control and configuration of the Wahoo is very flexible and powerful. Although you can access all of this power from the Wahoo’s control panel, to make it faster to give you an overview of all the settings, we have provided a Desktop Editor Software application that runs on both Microsoft Windows and Apple OSX.

You can run this beside your other audio applications to give you quick and simple access to any configuration parameters you want to adjust on the Wahoo.

Full details of the Desktop Editor Software are provided in the pdf manual. This section gives a brief introduction to what’s possible.


Preset Edit

You can view, edit, save and delete presets. To make setup of the filter as intuitive as possible an interactive graphical control lets you simply drag filter “hi” and “lo” around and hear the difference. The live filter positions are shown in real-time so you can understand how it works to help you design new and interesting sounds.

When two filters are used together it is possible to create vowel sounds, to achieve vocal sounds that are just not possible on single-filter pedals. A special “vowel” mode of the interactive graphic control makes it trivial to dial-in the vowel sounds you want.


Setup and Utility

Various utility features let you configure the basic operation of the Wahoo.

User presets and the settings of the Wahoo can be saved to, and loaded from, files. This lets you backup your configuration and allows you to exchange your favourite presets with other Wahoo users.
