I have sold way too many guitars that I figured I'd never sell, so I am hesitant to say there is one that I would NEVER sell. The only one that I would be unlikely to sell is a custom guitar I had made by a local luthier. It really could cover most of my bases if I needed it to. It's a dread with sinker redwood over walnut. The fretboard is ebony, as is the bridge. The inlays and neck were made to my specs. I doubt I would try to sell this one.
