Just picking this up afetr a pause. I'm attempting to locate a suitable sort of plastic sheet for this. The truss rod covers I need to make are for Overwater 'Original/ C type' basses. An email to Overwater on the subject remains unanswered. In a phonecall I had with Chris a while ago, I believe he said, if memory serves: 'we don't have those anymore' when asked about truss rod covers. So anyhow, the DIY route seems the most sensible/economical. Anyone got any thoughs about what type of plastic to use. I've found 4mm sheets of bakelite/phenolic resin (in black) on amazon, they look the part, but f anyone has actually done this before, I'd appreciate a steer!
