There’s just something about an Octaver that separates the men from the boys when slinging a six-string (or seven-string). Get your guitar sound another rung up the ladder with an effect that is bold and a bit on the psychedelic side. Rocktron’s Reaction Series pedals are built into a rugged metal slim form factor chassis, taking up as little space as possible on your pedalboard. The Reaction Octaver is a TRUE BYPASS pedal: when you turn it off…it is out of your signal path! Controls include BLEND which controls the Mix between the original input and the Low Octave effect. HIGH FILTER controls the overall Treble content of the effect. BASS FILTER controls the overall Bass content of the effect.
