What kind of guitar have you got man on bike? I've been wanting to get a new guitar for ages and the animal products in them have bothered me. Years ago I tried to find out more about it, but didn't find much.
Pretty much all decent quality guitars will have pearl inlay. The glues used on acoustics are most likely not vegan. AFAIK guitar strings are fine. I remember reading somewhere that Andres Segovia was using synthetic strings back in the fifties.
The only option that my conscience could deal with is getting a luthier to make me a guitar, but my bank account can't deal with that option.
Of course, air guitar is always an option
