Movall effect pedals are developed and manufactured by Caline. Accordingly, the manufacturing and sound quality are high. The pedals feature an aluminum housing and are designed in a compact format for space-saving placement on the pedalboard. They are powered by a 9V DC power adapter (center negative) which is not included. Size: 11 x 6 x 3 cm (LxWxH). With its thick, vintage-analog flanger sounds, this pedal adds entirely new dimensions to the pedalboard. With just three knobs, it achieves not only subtle modulation but also the legendary jet plane flanger sounds. Power requirement: 50 mA. True bypass.
