Mu-Tron Flanger

“Some flangers give you a wide range of effects, but lack the expressiveness of pedal control. Others give you a pedal, but limited sound range. Mu-tron’s new Pedal Flanger offers you both. You get a wide variety of effects like slap-back echo, card-board tube, hard reverb, vibrato, and double tracking, plus expressive pedal control, all in one professional package. Our new Pedal Flanger includes Mu-tron’s smooth and reliable Opti-Pot pedal, which stays free of hum and noise under all types of lighting and environmental conditions. LED status indicators let you know which functions are in use before you start playing. Mu-tron’s new AC powered, low-noise circuitry delivers the cleanest studio quality flanging on the market, at any price.”
