One Control Butter Yellow Auto Quack - Envelope Filter / Auto Wah

The One Control Butter Yellow Auto Quack (BYAQ) is an envelope filter / auto wah that reacts to the dynamics in the signal. The BYAQ was specially adapted by Bjorn Juhl to the range of electric guitars and electric basses and comes with a narrower range than comparable pedals. The Mellow/Bright switch on the side can be used to select a flat, narrow or a high, wide filter range. The pedal generates musical wah sounds and reacts precisely for fast rhythm sequences. The starting point of the filter can be set with the Bias control, Sensitivity determines the level from which played notes trigger the filter and Decay determines when the filter closes.
