I have a Christopher hybrid from 2006 that is starting to show a crack in the gloss finish along the seam between plates from the saddle up several inches (maybe 20ish cm) towards the bridge. I have several questions. 1. Anyone else have this happen? How common is this. 2. How is the gloss finish to work with for luthiers? 3. I assume that the plate will need to come off and be reglued with patches inside. 4. I live in suburban Chicago. Now that Classic Contrabass has closed up shop, who would you recommend? I would be willing to drive as far as Madison or Milwaukee as well. Luckily, I have a friend's plywood on loan.
