The Aria Flanger pedal is an excellent addition to any pedal board offering a wide range of sonic colour. Take it from mellow psychedelic swirls to all-out Van Halen style rock n' roll with total control over every parameter in this well-designed and affordable pedal. Like all Aria pedals, the steel chassis body is durable and sturdy for a long career in any effects chain. Would combine well with the Aria Short Delay or Chorus for atmospheric tones or the Aria Overdrive/Distortion for a searing lead combination. Runs on 9V batteries or AC adaptor.
