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?

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 filter 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 filter 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 suited ideally for lead breaks. Play around with it and you will find that there are a lot of possibilities, all the way to a searing razor edge off the hook vibe controlled by your pick attack.

Level control determines the output level of the effect. An included distortion button gives you a little more "dirt" when playing. 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.

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, but it is recommended to place 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 find the sound you personally prefer.
