Precautions

Introduction:
Are you searching for something new to add to your
setup and spice things up? Are you a guitar player who
wants to add a crazy, phasey and downright out of sight
twisted effect to your pedal arsenal. Maybe you are a
bass player searching for something that will give you
that funk with lots of punch? Rocktron aims to please
that eclectic wild streak deep inside every musician with
the Reaction Dynamic Filter.
The Reaction Dynamic Filter utilizes harmonic phase
shifting effect that sweeps the frequency spectrum from
high to low providing a unique one of a kind sound.
Since a dynamic lter is triggered by your pick attack,
the harder you pick the string, the higher the resonant
frequencies become. The SENSITIVITY control
determines the frequency at which the lter will begin
its phase shifting.
For bass players, lower SENSITIVITY settings provide
a funky walking talking swanky arpeggio effect tracking
your pick dynamics to produce a smooth and cool feel.
Turn on the DISTORTION to make it growl.
For guitar players higher SENSITIVITY settings
provide a more expressive “zipper” effect that is ideally
suited for lead breaks. Play around with it and you will
nd that there are a lot of possibilities, all the way to a
searing razor edge off the hook vibe controlled by your
pick attack!

Introduction continued....:
LEVEL control determines the output level of the effect.
We have also included a DISTORTION button to give
you a little more “dirt” when playing.
Rocktron’s Reaction Series pedals are built into a
rugged metal slim form factor chassis, taking up as little
space as possible on your pedal board. The Reaction
Dynamic Filter is a TRUE BYPASS pedal: when you
turn it off…it is out of your signal path!
The Reaction Dynamic Filter can be placed in the
signal chain before or after a distortion. We recommend
placing it after. If using multiple pedals such as delays
and other modulation effects, try the Reaction Dynamic
Filter in different parts of the signal chain until you nd
the sound you personally prefer.

The footswitch on the Reaction Dynamic Filter 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.

How to change the battery:
To change the battery, remove the thumb screws on
the top of the pedal and remove the battery com-
partment cover. Remove the old battery and replace
it with a new 9V Alkaline battery. Replace battery
in the same area as the old battery was located.
Place the battery compartment cover on the pedal
and re-insert the thumb screws.
Save yourself tons of money in batteries by using
the Rocktron DC OnTap Universal Power Supply
to power this pedal (sold seperately). The Rock-
tron DC OnTap provides a constant ow of power
to the pedal, unlike a battery that will degrade over
time. The Rocktron DC OnTap Univeral Power
Supply can also power up to 20 pedals and can be
used with both 110V and 220V power sources.
