The Carl Martin Axis Flanger is a small flanger pedal loaded with features. Plus, the controls have been simplified to give you all the finesse you had with the Carl Martin Classic Flanger but in a reduced size. Complete with a buffered Bypass footswitch for on and off control (indicated by an LED), Speed, Depth, Pre-delay and Feedback controls, the Axis Flanger comes in a machined aluminum case finished in psychedelic purple with those Carl Martin graphics. The Axis Flanger must be powered by a regulated 9v Power Supply like the Carl Martin DC Factory.
