The response of the effect is highly interactive with the dynamics of the input signal - this makes it possible to vary the response at will via slight adjustments to playing technique. Therefore, it may take some practice before the response of the auto-wah can be wilfully controlled in order to achieve a consistent sound.
The effect's response is highly responsive to the input signal's dynamics, allowing for adjustments in the response by making slight changes to playing technique. Therefore, it may take some practice before the auto-wah's response can be reliably controlled to achieve a consistent sound.
