My book is about a singer/songwriter who wins a Grammy and plays a Taylor guitar. Is it okay for me to reference these by their brand name? I tried writing the Grammy scene generically, but it just comes off as hokey. Maybe I could give it another name and in my characters' universe that's what it is called? But it always irritates me when I read books that do that. Some brands are so well known that any attempt to change them comes off as lame. And the Taylor guitar is sort of a play on my MC's last name, sort of important to the story with themes of destiny and such. I know it's fiction, but im just trying to be as authentic as I can. Any thoughts on using brand names in fiction?
