Avant-Garde, from Glou-Glou, is an expansive multimode stompbox that brings users some of the best synth-style effects around. The pedal is a combination of a filter and a phaser that also sports two independent envelope controls. It features a simple LFO with rate and depth controls for modulating various aspects of the modulation matrix.
