This is a compact optical envelope filter?commonly known as an auto-wah?based on the Classic Optical Envelope, which was once a popular model in the Vintage Series.

While the Classic Optical Envelope used two footswitches to toggle between high-pass, band-pass, and low-pass filters, the S Series?with its more compact design?now uses a pin switch instead.
In addition to the tone control, level, and gQh (which adjusts the frequency), the control panel now features a new gAttackh control that allows you to adjust the sensitivity to your picking.

The Ottawa, an auto-wah, is an envelope filter that mimics the sound of a wah pedal based on the intensity of your picking attack?without needing to press the wah pedal or manually adjust the frequency.
Even if youfre not interested in the disco sounds of the f60s and f70s or other music that calls for this unique sound, this pedal is perfect for solos and rhythm work, so you should definitely give it a try.

It features three controls?High, Band, and Low-Pass Filter?as well as adjustments for bandwidth and attack, and Level and Tone. By varying these settings, you should be able to discover your own unique, original sound.
It shows some signs of use, such as minor scratches and dirt, but it functions perfectly.
Note: This is the unit only.
