HornFX Review
Interface: 3/5
This auto-wah is more on the simple side. It is easy to find a good setting, but not as manipulable as some may prefer. The decay knob is a quality feature
Versatility: 3.5/5
There are not many different sounds that this pedal can make. The filter itself remains constant, but its sweep and resonance can be changed to find subtly different sounds
Clarity of Effect: 4/5
The filter speaks quite nicely. Sometimes, there may be a slight overdriving of your tone at points in the peaking of the filter, but nothing to hinder its use.
Complexity: Simple
Live application: 3.5/5
Without presets and without deeper controls, this may not be the first choice of someone looking to get a lot out of their envelope filter. This pedal is more attuned to the person that wants to just find one setting that works and turn it on when they want to use it.
Product Information
Hand-made in Finland premium quality auto wah pedal.
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 instrument, 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.
Like all Hand Wired MP pedals, SWAW is hand made in Finland using only premium components, to give years of trouble free operation with superb musical tone.
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 techniques. Try also adjusting guitar volume between 8 and 10 to further expand use.
