AUTO FILTER (AF-9)

New look - Same great sound.

You may have noticed that the Maxon AF-9 Auto Filter has undergone a facelift. 

Specifically, the Sensitivity & Peak faders have been replaced by rotary pots and the slider switches are now toggles.

This change was made out of necessity due to the discontinuation of the fader pots that had been used on this model for nearly 40 years (original release date was 1981).

While these changes may have been necessary, Maxon saw no reason to update the AF-9’s classic, watery, 3-dimensional filtering that so many players have to come to count on over the years.  So, you can expect the latest version of this classic quacker to stand up to the original.

While change may be inevitable, if it ain’t broke, then don’t fix it.

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.

"The Maxon Auto Filter is one of my favorite "go-to" pedals. This really helps you give your playing a human voice without sounding like you just stepped on an effects pedal. It is really special and you can hear it on tons of my recordings." - Marty Friedman (ex-Megadeth, Cacophany)
