Rocktron Reaction Phaser

Rocktron · pedal

The Rocktron Reaction Phaser is part of the Reaction series of analogue pedals, producing phase shifting — a series of moving notches in the frequency response, which is a subtler and more swirling effect than the flanger in the same line. The Reaction range covers standard effect types at accessible prices. Independent coverage of this specific model is limited, so no control or stage-count specifics are asserted here.
