Interesting. So, not only you, but everyone you know has only three fingers?
Well, certainly we can accommodate you with a custom guitar. But before you go to the extra expense of going custom, consider that Django Rinehardt was, and Phil Keagy is a marvelous player(s). Neither had four fingers (and thumb). Perhaps you might be able to do more than you think with just three fingers!
We don't currently have a representative in Springfield for you to test our guitars. If you could tell me which State Springfield is in, I would be glad to tell you our nearest distributor.
