Tired of the same old effects? You say you want something a little bit... different? The FM4 Filter Modeler, part of Line 6's award winning line of Stompbox Modelers, gives you an array of vintage and new effects from just a wee bit odd to full frontal freaky! From the gentle auto-wah of an envelope filter to the complete wackiness of mutated VCO controlled ring modulators, FM4 can get as strange as you wanna be.
