I've had the idea of a keyless, open-ended chanter with a flattened seventh that would be played with NSP style fingering, primarily inspired by Dixon tunes. Julia very kindly gave me a keyless chanter to experiment with, but I haven't had the heart to open up the bottom or fill and redrill the 'f' hole. It's been a lot of fun to play as is.
