Hey all! I am new here, I was hoping someone could help me with something. My guitar is a 7 string Kiesel Osiris multiscale (scale length 25.5" treble side, 27" bass side ) I want to tune it to C standard, ( C# G# E B F# C# etc.. ) My question is, which strings / gauge should I use for this tuning? Longer scale allows me to use lighter gauge, with great tone, correct? Any help is appreciated, I am new to this. Thanks! P.S here she is!
