Try this: Ask any of the 500 people who have visited your site today to tell you the name of that Linux flavor for Guitar players. I'd be surprised if a single one got it right first try.
Now imagine it was called "Hendrux - a GNU/Linux distro for recording musicians". Pretty much all of us would be able to repeat that back to you (though a few might misspell the name).
Names have value. They send messages. GNUGuitarINUX sends the message that "The author thought this was a good name, so chances are the project itself will be every bit as opaque. Best stay away unless you have a lot of time to spend getting it working."
