I bought the FBV Shortboard MkII to go with my Spider IV 150 on 7 December 2011 and I now have a critical problem with the stomp switch I use most - the patch selected marked 'A', bottom left. Basically it has started to become erratic as to whether it toggles or not - sometimes I stomp, and it works, but every other time I stomp, the switch does not operate.

I have a gig coming up in March so obviously I want to fix it before then as it can completely throw me out when changing patches mid-song as I did during rehearsal last night....

Can anyone help? Is this a common problem? Any simple fixes (I know how to use a soldering iron...)? Is it a Line 6 Repair Only job, in which case how am I going to get it fixed before March?

Any advice gratefully appreciated (think I have posted in the right forum, but apologies if not...)
