Rocktron Reaction Flanger

Rocktron · pedal

The Rocktron Reaction Flanger is a member of the Reaction series of analogue effect pedals, producing the sweeping comb-filter effect that comes from mixing a signal with a short modulated delay of itself. The Reaction line covers standard effect types at accessible prices rather than pursuing boutique voicing. Independent coverage of this specific pedal is limited, so this description stays with what the effect type and series position establish.
