Come Fly Away. Originally achieved by physically pushing the tape flange on a reel-to-reel recording device, flanging is one of the earliest guitar-effects. The Hammertone™ Flanger delivers dramatic, rushing jet stream waves and subtler, swirling tendrils of modulation. Pedal board-friendly top-mounted in & out jacks and true bypass footswitch mean it will integrate seamlessly into your rig.
