Introduction
Congratulations on your purchase of the Rocktron
Heart Attack.
The Heart Attack Dynamic Filter pedal produces a harmonic
phase shifting effect that sweeps the frequency spectrum from
high to low. It is ideally suited for bass and can also be used by
guitarists.
The dynamic filter effect is triggered by pick attack. The harder
you pick the string, the louder the effect. The Sensitivity control
allows for frequency adjustment of the effect. Lower settings
provide for a lush, smooth feel - ideal for locking in with a
drummer and providing a solid low-end. Higher settings provide
a more expressive effect that is ideally suited for lead breaks.
Play around with it - you will find that there are tons of possibili-
ties as the effects volume and sound is mainly produced by your
pick attack!
We have also included “distortion” to give you a little more “grit”
when playing.
The easy access battery compartment will make changing batteries
during a gig a breeze. We have also equipped it with a super
bright blue LED so you will know when the pedal is on...it is also
just plain cool!
Enjoy

Hints and Tips:
The Heart Attack pedal usually sounds better when placed after
distortion in the signal chain. However, the Heart Attack can be
used either before or after a distortion.
If using multiple pedals such as delays and other modulation
effects, try the HeartAttack in different parts of the signal chain
until you find the sound you like best.
If you have an effects loop in your amplifier - try putting the Heart
Attack in the effects loop for a different sound (please follow all
instructions in your amplifier manual when connecting to your
effects loop).
