Maxon 9-Series AF-9 Auto Filter Pedal

Our Take:

Maxon's AF-9 Auto Filter has been a favorite of musicians since its release back in 1981 - offering a potent mix of auto-wah and swept filter effects that adds gorgeous, watery, three-dimensional filtering effects reminiscent of the most sought-after vintage units. The AF-9 may look slightly different than it used to, but rest assured: it's still the same intuitive, powerful, and compact pedal that it always has been.

Maxon's Take:

The Maxon AF9 Auto Filter takes the most desirable auto-wah and swept filter effects and offers them up in a compact, user-friendly package. Opto-coupler circuitry produces the shimmering, watery filtering of legendary vintage units. Threshold and Peak sliders control the degree of effect; while Range and Drive switches determine range and direction of the filter sweep. Three selectable filter types (Low Pass, Band Pass, and Hi Pass) and a frequency range of 100 Hz – 4 kHz allow the AF9 to function with virtually any instrument or input signal.
