  • Page 2: Safety - Read This First

    Important safety information. Read the following information carefully and keep all instructions for future reference. ! ! ! ! Do not open any part of the Wahoo case other than the battery compartment. There are no user- serviceable parts in the Wahoo. ! ! ! ! Do not expose the Wahoo to rain, liquids or moisture of any kind.

  • Page 3: Quick Start

    Owner’s Manual Quick start This manual is a comprehensive guide to the Wahoo. To start using it as quickly as possible, follow this short guide. Please refer to the rest of the manual for detailed operating instructions. Connect your guitar/bass to the jack of the Wahoo.
  • Page 4 For guitar and bass The Wahoo is designed from the ground up to be perfect for guitar and bass. We know that many musicians play both instruments and don’t want to compromise when an effect is designed for the Wahoo ©...
  • Page 5 Wahoo parameters can perfectly match guitar and bass, and you can save and switch between instrument-specific set-ups. Of course, the Wahoo can also be used on other instruments such as keyboards. You don’t need to restrict your creativity to guitar and bass!
  • Page 6 Using the Wahoo In the rest of this manual, we cover everything you need to know about the Wahoo from how to connect it to your rig, to how to power it and how to delve in and create your own presets.
  • Page 7 This also has the advantage of not boosting any noise produced by the Wahoo. You can also connect the Wahoo to the effects loop of your amp: connect the output of your guitar to the input of your amp, then connect the “send” of your amp to the Wahoo...
  • Page 8 Wahoo. The 9V power supply that you use should be capable of providing 500mA and have a 2·1mm centre pin connector. Note that the Wahoo has been designed so that either polarity (tip-positive or tip-negative) can be used. •...

  • Page 9: Selecting A Factory Preset

    (page 31). The Wahoo has two modes: Preset Select mode and Preset Edit mode. By default, it is in Preset Select mode and the display alternates between the 3-character preset name and the preset number: either F00–F99 for factory presets 0 to 99 or P00 –P99 for user presets 0 to 99.

  • Page 10: Lock Switch

    . When this switch is in the LOCK locked position, the Wahoo is in Preset Select mode and none of the parameters can be edited or saved: the only thing that you can do is change between presets. If you try to make a change when locked, LoC is shown briefly on the numeric display.
  • Page 11 Note 2: In foot-operated preset selection mode, you can still use the buttons as normal to select presets, and to increment/decrement in 10s if required. Wahoo © Copyright 2012 Sonuus Limited...

    Owner’s Manual Creating your own presets You can create and store up to 100 user presets on the Wahoo. The steps for creating a preset are straight-forward. Creating and saving a user preset Creating and saving a user preset Creating and saving a user preset...
  • Page 13 This controls the filter mixer: the proportion of filter 1 and filter 2 that form the LEVEL output of the Wahoo. 0 gives 100% filter 1, 100 gives 100% filter 2. Note that, to make editing simpler, the active filter will automatically switch to 1 or 2 when 100% of that filter is selected.
  • Page 14 Owner’s Manual unaffected by the Wahoo filters. 100 (wet) means only the filtered sound is present in the output. This parameter be used to retain some of the sonic character of the original instrument sound. For example, for bass envelope filtering it is common to retain some dry signal to ensure the initial attack of notes is retained.
  • Page 15 Reverse filter sweeps Reverse filter sweeps It is simple on the Wahoo to create reverse (inverted) filter sweeps: simply set freq-hi to be smaller than freq-lo. “hi” and “lo” refer to the modulator position: when the footpedal is in toe-down position (or the envelope follower is at a maximum), the value freq-hi is used, whether this is greater than, or smaller than, freq-lo.
  • Page 16 The roll-off is measured in dB per octave and the low-pass filter in the Wahoo has a roll-off of 24dB per octave. The band-pass filter has a roll-off of 12dB per octave on each side of fc. Note that this means the low-pass filter is more effective at removing frequencies above fc than the band-pass filter.
  • Page 17 Vocal sounds i.e., To get very vocal-sounding filter effects, you must use both Wahoo filters working together ( operating in the same mode so that they track each other). Doing this lets you approximate the pairs of dominant resonances that are present in the vocal tract when forming vowel sounds. See “Creating vowel sounds”...

  • Page 20 The trapezoidal waveform is highly configurable: examples of trapezoidal waveforms are shown below. In the Wahoo, the shape of the trapezoid is controlled by the parameters ramp up and ramp down, referring to the left and right sides of the waveforms shown. One cycle of the trapezoid waveform is represented by 100 time units.

  • Page 23 Pitch-track (trA). In pitch-track mode, the cutoff frequency of the Wahoo filter is set to follow the pitch of the notes that you play. There are three parameters that control how this happens. The pitch tracking can be offset from the pitch of the notes you play by adjusting the FrE frequency sub- parameter—...
  • Page 24 Top Tip: Pitch tracking is optimised for different instruments. You can choose the instrument setting in the custom settings (see “Custom settings” on page 27) to select between guitar, 4-string bass and 5-string bass. Wahoo © Copyright 2012 Sonuus Limited...

  • Page 25: Midi Operation

    Owner’s Manual Creating vowel sounds To create convincing vowel sounds, you need to use both Wahoo filters working together to produce the characteristic frequency components of the desired vowels. The table below shows typical cutoff frequencies that can be set on each filter to obtain each vowel sound. Note that these values are approximate and are a good starting point.

    The custom settings are not stored in a preset, they are stored in the Wahoo itself. They take effect from when they are changed. They are not changed by switching from one preset to another.

    Wahoo in a particularly hot or cold environment. Calibration has the best results if the Wahoo has been on for at least ten minutes so it can warm up to a stable temperature. If you calibrate the Wahoo in a warm room straight after you have brought it in from a cold car, the calibration may not remain accurate as the Wahoo warms up.
