Modelling flange effects pedal that allows you to experience the entire history of popular flanging effects in one compact box – the whole history of analogue, tape and digital flanger effects at the touch of a footswitch. It is powered by Behringer's Real Sound Modeling technology creating a flange in a class of its own. The RSM chip provides this pedal with the power to simulate the resonance and character of the perfect acoustic environment, resulting in a sound that is nothing short of transcendental. It provides 12 kinds of flange to choose from: random, vintage, chorus, triggered up, triggered down, saw up, saw down, envelope down, envelope up, sine and step flange effects. Sound can be further shaped by dedicated Model, Speed, Feedback, Depth, Polarity and Time controls. Other features include a status LED for effect on/off and battery check and first class electronic on/off switch for highest signal integrity in bypass mode. It runs on 9V battery or the Behringer PSU-SB DC power supply (not included).
