Rocktron EN50082-1, Instruction Manual

Introduction

Thank you for purchasing the Rocktron Reaction 

Chromatic Tuner.  Simple to use, the Reaction Tuner 

makes things easy with a large segment note display 

that offers easy viewing.  Flashing FLAT and SHARP 

LEDs also make it easy to see just where your tuning 

is and how close you are to getting into tune.  A bright 

blue LED shows you precisely when you, in fact, are 

in tune.  

When turned on, the Reaction Tuner output is muted, 

thus allowing for silent tuning.  The Reaction Tuner 

offers a calibration button that allows you to adjust the 

tuner in order to tune to instruments that are “out of 

tune”, such as an old piano.  

Rocktron’s Reaction Series pedals are built into a rug-

ged metal slim form factor chassis, taking up as little 

space as possible on your pedalboard.  The Reaction 

Tuner is a TRUE BYPASS pedal: when you turn it 

off…it is out of your signal path!

The footswitch on the Reaction Tuner controls On/

Off status as shown by the LED indicator.  Reaction 

stomp boxes run on a 9V Alkaline battery, or may 

also be powered by Rocktron’s DC OnTap Universal 

Power Supply adaptor.
