I just purchased a 2019 Gibson Memphis 335 ...my dream guitar. QC is spot on but I noticed the truss rod cover looks to be the basic version rather than the stepped 2 ply with the f hole engraving that I ‘ve seen on these guitars. I’m wondering if it’s simply an error at the factory. So I contacted Gibson to order the proper part and they didn’t seem to know what I was referring to. I contacted Sweetwater. Same thing. I did a thorough search on the Internet and came up with squat. So my question is this: does anyone know what the deal is with this elusive little piece of plastic?
