Description
Description
In the Classic Optical Envelope, two foot switches were used to switch between high-pass, band-pass, and low-pass filters, but with the miniaturization of the S Series, this was changed to pin switches.
In addition to the control section, which includes a "Q" that adjusts tone, level, and frequency, the new "Attack" control allows you to adjust sensitivity to picking.
Ottawa is an auto-wah with an envelope filter that mimics the sound of a wah pedal depending on the strength of your picking attack, without the need to step on a wah pedal or manually adjust the frequency.
Even if you're not interested in the psychedelic sounds of the 60s and 70s disco or other music that requires this unique sound, this pedal is perfect for solos and rhythm work, so I highly recommend giving it a try.
There are three controls - high, band, low pass filter, bandwidth and attack adjustment, level and tone - which you can adjust to find a more unique and original sound.
It has a smooth, comfortable feel and can be used for a wide range of purposes, from standard use as an auto-wah sound to creating tricky tones.
Attack knob: Adjusts the sensitivity of the auto-wah effect. Tone knob: Adjusts the tone quality with a high-cut filter. Level knob: Adjusts the effect level. Q knob: Adjusts the filter bandwidth. Filter switch: Selects the filter type.
