Hi folks and luthiers ! I'm very interested in the whole extended range thing and I wondered where is the end of adding more and more strings. There are 9-strings at the moment but I personally dream of a non-doubled 12-string tuned: C# F# B E A D G C F Ab D# G# Would this be possible on a 34.5" scale speaking of string gauges and so on ? What would you have to keep in mind when building such a monster ? Thanks for any input !
