Up for sale, a 1970s Maxon FL-305 Flanger in excellent condition and in perfect working order. A pedal that offers a pioneering amount of control for a flanger of its era, the five knob layout ensures that the player can tailor effect to certain frequencies. The circuit is untouched, powered by a pair of 9v batteries. The enclosure shows only light wear, the graphics are in great shape, and the original knobs are present.
