The Zero Point Flanger is the most direct analogy to studio tape flanging that anybody has come up with. It is a REAL TIME effect not a typical modulation effect. That is to say, unlike all other pedal flangers, there is no LFO that presents a predictable up and down swooshing sound, the trite flanger effect that died in the 80s. Thus there is no need for extraneous knobs or switches. It is a straight-forward pedal that has only one powerful control that behaves like pressing and holding your thumb on tape flange.
