I've been browsing the forum for a few hours and found information on an apparent recurrent issue with the nose bridge couplers of some X-Metal models degrading. I had my Juleits stored for some time and when I got them out, they were loose and saggy from the nose bridge. For what I have learned, I can get the couplers and replacements pins from LINEGEAR, but, how difficult is to to perform the actual swap? Can anybody share their experience? Thanks!
