I just got that very bass pictured.
It has a 30" scale (though measuring, looks more like 30.5")
The B seems rather mild.
I'd like to try it E to C.
Perhaps someone could suggest a 5-string set that would work, or a 6-string set I could leave the B off of?
Or possibly a B to G set that could be more effective at 30"?
I'll address nut issues as they arise.
