A big box version of EHX’s beloved funk machine, this QTron delivers super phat filtered sounds with a broad frequency response to ensure compatibility with just about any instrument.\u003cbr\u003e\n\u003cbr\u003e\nThere’s nothing quite like experimenting with an envelope controlled filter: whether you end up in bubbling Bootsy Collins bass territory or quacked-out Jerry Garcia cocked wah soundscapes, there are arguably very few faster shortcuts to a slew of unique sounds. Controls include Peak, Gain, Range, and Mode (Low Pass, Band Pass, High Pass, and Mix BP\/Dry) knobs, with two-way Drive (Up\/Down Filter Sweep) and Range (“Hi” with overtones emphasized and “Lo” with vowel-like emphasis) switches. This QTron also features independent Wet and Dry outs.\u003cbr\u003e\n\u003cbr\u003e\nThe large polished aluminum enclosure shows some light surface wear, with clean graphics and original ridged pointer knobs.","brand":"Electro-Harmonix","offers":[{"title":"Default Title","offer_id":49151187779840,"sku":"ISI870894","price":349.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/4437\/4714\/files\/medium_c098f932-0cb3-4231-8c74-bcd4279e5437.jpg?v=1786213567","url":"https:\/\/mmguitarbar.com\/products\/electro-harmonix-q-tron-envelope-controlled-filter-effects-pedal-w-power-supply","provider":"Mike \u0026 Mike's Guitar Bar","version":"1.0","type":"link"}
