One Control BUTTER YELLOW AUTO QUACK Whether you want to add expression to your lead tone, funky cutting, or bouncy bass, using an envelope filter can greatly expand the expressiveness of your songs and playing. The One Control BUTTER YELLOW AUTO QUACK is a practical pedal that combines the best of envelope filters in a very small size. Many auto-wah and filter pedals have many control knobs and large chassis. As a result, when you put a filter in your pedalboard, it may only be when you play a certain song, or it may be important to use the filter. But even if you only use it for two seconds in a song, an envelope filter has the power to add a new expression or a new texture to a song. We want an envelope filter that is easier to use, yet has a sound that can take center stage. Guitarists and bassists around the world have been asking for this. The Butter Yellow Auto Quack is an envelope filter that can be used with a variety of instruments, including guitars, basses, and active and passive pickups, by simply setting three control knobs.There is a MELLOW/BRIGHT toggle switch on the side of the unit that allows for a wide range of filter tones. The BRIGHT mode applies the filter from 70Hz to 3kHz, giving a more intense swell or scream-like tone. MELLOW mode filters from 70Hz to 600Hz, creating a warmer, wah-pedal-like tone, also suitable for bass. The BIAS control sets the starting position of the filter, the SENS adjusts the movement to match the instrument's characteristics and pickups, and the DECAY controls the length of time the filter is applied. Just like that, you can create the tone of the filter. From slow wah-like movements to quick "quacks," many filter tones are packed into this pedal.
