Line 6 is a great company and has always been good to me, although they put too much faith in their service centers, ie, when I call them for help, they have a lack of interest and know a hell of alot less than me( cant talk to the tech to see if he started last week and they all seem to need to contact Line 6 for answers) especially when it comes to my legacy products. Anyway I dont know whet the answer is, but I wish more parts were available, all we have is fullcompass.
