I saw that you can get a new lever for existing d tuners that will allow you to set to D and C in two stages. Sounds interesting. Does anybody here have a a setup like that? Does it work well? I've been using the regular D tuner and the fingering is OK but going to C on the E string would make it much harder to wrap your brain around the new fingerings. Is it in any way practical at all to drop the E down to C with that kind of a shift?
