Definitely the (modern, anyway) Gibson nitro seems to smell and feel different than the (modern) Fender nitro. The only way I can describe the Gibson smell is "hot chocolate".
I got into an argument/discussion on another forum whether this is smell is the guitar/finish or the case. Some are adamant that it's the cases Gibson uses. I am firmly in the camp that these people are all unobservant idiots :lol: (one of my Gibsons was separate from its case for a long period, the case no longer smelt of chocolate at the end of that, the guitar still did... put the guitar back in the case, and the case started smelling like it again...)
