Precautions

Introduction
Are you searching for a Digital Delay stomp box
that delivers great sound and outperforms the
competitors when it comes to sonic quality? Pick
up the Rocktron Reaction Digital Delay and surprise
everyone, including yourself!
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 Digital Delay is a TRUE BYPASS pedal:
when you turn it off…it is out of your signal path!
The Reaction Digital Delay is very easy to use.
Controls include LEVEL, which controls the output
level of the effect. MODE determines whether the
Delay time range is Quick (62.5 ms – 125 ms) or
Extended (125 ms – 250 ms). REGEN controls how
many echoes you hear, while TIME controls the
Delay Time selection.
The Reaction Digital Delay has all the smooth full
bodied tone you expect in a delay pedal. If you are
a rocker, we’ve got your back! Just set the Reaction
Digital Delay mode to Extended, then turn

Introduction continued....
the Time control to nd that classic rock phrasing
echo. Country pickers or Rockabilly jammers, set
the Reaction Digital Delay mode to Quick and dial
up your favorite slapback!
Most players nd that delay pedals will sound better
when placed after distortion. If you are using a
distortion pedal, place the Reaction Digital Delay
after the distortion pedal in the signal chain. If
you are using your amplier’s distortion, place the
Reaction Digital Delay in the effects loop section of
the amp, (making sure to follow the instructions in
your amp manual when using the effects loop).
The footswitch on the Reaction Digital Delay
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.

to power this pedal (sold seperately). The Rocktron
DC OnTap provides a constant ow of power to the

also power up to 20 pedals and can be used with both
110V and 220V power sources.
