SA246 Aftershock Bass Distortion User’s Guide 20
The resistance of the expression pedal does not matter. The Aftershock will automatically adjust
itself to the range of the expression pedal when it is configured.
Most expression pedals use a ¼” plug, but the Aftershock’s CONTROL PORT is 3.5 mm. To make the
connection, a simple TRS plug converter (1/4” to 3.5 mm) can be used.
Note that although the CONTROL INPUT expects a 4-contact TRRS plug, most 3
rd
party expression pedals
use a 3-contact TRS plug. This is OK – using a simple 3-contact TRS plug converter, the expression
pedal’s output will be connected to the Aftershock’s CONTROL INPUT and the extra contact is ignored.
Configuring the Expression Pedal
It is easier than ever to set up expression control using the Aftershock’s new calibration and mapping
method. When the expression pedal is connected to the Aftershock, follow these simple steps to
calibrate it and map it to control different effect parameters.
1. Press the CONTROL INPUT button to turn on Control Input mode. The CONTROL LED should be lit
green.
2. Press and hold the CONTROL INPUT button until the CONTROL LED begins to blink slowly
(approximately one blink per second).
3. Move the expression pedal over the range of motion you would like to use to control the
Aftershock. If you would like to use the expression pedal’s full range of motion, then make
sure to move the pedal all the way from its minimum position to its maximum position.
Note that you can create “dead zones,” if desired, by only moving the expression pedal over
a limited region of its full range of motion.
4. After setting the expression pedal range, click the Aftershock’s footswitch once. The
calibration is now complete, and the CONTROL LED will blink faster (about 2 blinks per
second). Now, it is time to map the expression pedal to the effect parameters.
5. Move the knob(s) you wish to control with the expression pedal to the minimum desired
position, then click the Aftershock’s footswitch. The CONTROL LED will now blink even faster
(about 4 blinks per second). Note that you may control one or more knobs with the
expression pedal, up to four total knobs.
6. Move the knob(s) you wish to control with the expression pedal to their maximum desired
position, then click the footswitch. The CONTROL LED will now be lit solid green. Note that
you may control one or more knobs with the expression pedal, up to four total knobs.
7. After setting the minimum and maximum knob positions, the parameter mapping is
complete.
Note: The parameter range can be inverted by swapping the minimum and maximum position of the
knobs during configuration.
External Switch used as Expression Input (Expression “Toggle”)
An external switch can also work as a sort of expression pedal that only has two positions: on and off.
The external switch can be either momentary or latching.
To use this mode, connect an external switch to CONTROL INPUT. The following plug configuration is
required:
