I came across Newtone through Jon Gomm who recommended them for his acoustic set. I have a set on my acoustic guitar now and they sound great, even on a cheapy Indonesian Fender. Well, five of them do as I managed to snap one when installing them (the perils of being a bass player who can be a bit rougher, I guess) so one is a used Ernie Ball, but it all adds to the character or something.
