I'm loving this logo. I'd love to see it on a white background, just the logo, since it will be used on many different colored backgrounds. I don't like the grey of "Inner". I don't know that it's necessary but anyway to incorporate a guitar or piece of a guitar, ie the head of a guitar?
I love this logo (#14). However, there's still something not working for me. I think it's the color. In your original design I liked that "inner" was a different color than "rockers". Just didn't like the grey. I'm thinking maybe you could play with "inner" being black or shades of dark grey/black. Can you make "rockers" more red than orange?
