What about classical guitar? I.e: Nylon stringed, Spanish guitar. I've played Beethoven and Bach pieces on one. Granted one can do that on an electric or steel string, but something about the timbre lends classical guitar to classical music. Plus it's the only style of guitar which really sees regular classical concert performance.
