{"product_id":"2000s-maxon-af-9-auto-filter-guitar-effects-pedal-japan","title":"2000s Maxon AF-9 Auto Filter Guitar Effects Pedal, Japan","description":"Up for sale, a 2000s Maxon AF-9 Auto Filter pedal in exceptional condition and in perfect working order. Produced in Japan, this Maxon pedal delivers wonderfully funky auto-wah and sweep effects. Designed to duplicate the tones of the iconic Mu-Tron III, the AF-9 uses special optical circuitry to recreate the watery, vowel-like envelope filtering that made the Mu-Tron a staple of ‘70s funk and soul.\n\nControls include Sensitivity and Peak sliders, with Filter, Drive, and Range switches. Sensitivity determines how much pick attack is required to engage the AF-9, while Peak controls the center frequency of the filter and affects how pronounced the wah sweeps are. The three-way Filter switch selects between Low Pass, Band Pass, and High Pass. The two-way Drive switch determines the direction of the sweep (Up\/Down), and the two-way Range switch determines the overall frequency of the filter (High\/Low).\n\nThis pedal is in exceptional condition, with just a few tiny marks on the enclosure, clean graphics, and a flawless serialized foil label on the bottom.","brand":"Maxon","offers":[{"title":"Default Title","offer_id":43645422076160,"sku":"148NA0022","price":274.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/4437\/4714\/products\/medium_7e3b58ad-e798-4ff5-af9c-63b542afcdde.jpg?v=1751507820","url":"https:\/\/mmguitarbar.com\/products\/2000s-maxon-af-9-auto-filter-guitar-effects-pedal-japan","provider":"Mike \u0026 Mike's Guitar Bar","version":"1.0","type":"link"}
