Hi All, i play a Martin BC-15E ABG, string tenor (ADGC). Has anyone experimented with unbalanced string tensions? I'm asking because I just tried a Thomastik C string (acousticore), which is considerably lighter in gauge than a regular steel C string, but it sounds great with my D'Addario phosphor-bronze ADG strings. If I leave on the lower tension C string, am I liable to twist my neck? Apologies if this is the wrong forum, but since it's a question about what a neck will take, I figure this is the place. Thank you!
