Hello all,

I'm having a problem with my FBV Shortboard MKII. When I switch the patches to use the pedal to control VOLUME or WAH, it doesn't work, no matter what I do.

So, I did read a lot of references and find out that I had to calibrate to make it works. Ok, I did it and still the same: it's not working properly (during the calibration procedure, I did follow the steps and I can see the Default 0 but it doesn't change to Default 127 as indicated.

Some important information of what I did trying to solve the problem:

1) I already change the cable and it's not the problem (some posts are saying this).

2) All the other functions are working fine (controling the effects, etc.), but the expression pedal doesn't work for Wah or Volume.

3) I also did the update to 1.4 firmware version using the software Line 6 Monkey as indicated by some posts I read. No results...

4) I'm following the calibrating procedures step by step and yes, I'm fully aware of how to do it (there is a video explain it very well on youtube).

5) The product is brand new and I never used before.

6) There is no damages on it.

7) Yes I'm using a Line 6 amp Spider IV 150 to calibrate the pedal.

Please, anyone could help me? I don't know what to do!!!
