This article will show you how to adjust the expression pedal tension on your HeadRush Flex Prime.
The adjustment bolt is located on the right-hand side of the Flex Prime, at the expression pedal pivot point.
To make the adjustment, you will need a 6 mm Allen key.
Make small adjustments to the bolt:
- Clockwise: Increases pedal tension
- Counter-clockwise: Decreases pedal tension
Make only small adjustments at a time and test the pedal movement after each adjustment. Do not overtighten or force the adjustment bolt.
Because the adjustment point is accessible from the side of the Flex Prime, the unit does not need to be removed from a pedalboard to make the adjustment.
