It would be helpful if you told us what you are connecting the FBV Shortboard to.

  Also, I recommend that you perform a calibration of the expression pedal to see if that resolves the problem:

  FBV Shortboard Calibration (Mk I)

  1. Attach the RJ45 cable from your Line6 device to your FBV pedal board. Once your Line 6 device is powered up, your FBV SHORTBOARD's LEDs should cycle and the display should read "LINE 6" with the backlight lit up.

  2. Move the ONBOARD pedal to the center position, roughly halfway between the MAXIMUM and MINIMUM position.

  3. Press STOMP + DELAY + REVERB and hold for three seconds to begin calibration of the ONBOARD pedal.

  4. Move the ONBOARD pedal to its MAXIMUM position (pedal all the way toe down) and press down hard enough to actuate the pedal's toe switch.

  5. Move the ONBOARD pedal to its MINIMUM position and press down (pedal all the way heel down).

  ***If you have an EXTERNAL pedal, hook it up to your FBV SHORTBOARD now and continue on to step  six. If you do NOT have an external pedal, simply turn OFF you Line 6 device, you are done calibrating.

  6. Move the EXTERNAL pedal to the center position, roughly halfway between the MAXIMUM and MINIMUM position.

  7. Press BANK DOWN + STOMP + DELAY and hold for three seconds, to begin calibration of the EXTERNAL pedal.

  8. Move the EXTERNAL pedal to its MAXIMUM position (pedal all the way toe down).

  9. Move the EXTERNAL pedal to its MINIMUM position and press down (pedal all the way heel down).

  10. Turn OFF your Line 6 device. You have just calibrated your EXTERNAL pedal.

  Lastly, if you purchased the FBV Shortboard in the US, you have a one (1) year warranty from the date of purchase.
