I'm a bit lazy and can't be arsed to keep drop tuning my basses so I have 1 kept at standard tuning (also drop D), 1in Eb tuning and 1 that I might keep at C A D G tuning as Im playing more stuff in that tuning but I'm finding the E tuned down a C far to floppy would it be better to put a B string on it and tune up to a C instead so the tension is better or would that put too much strain on a standard 4 string neck??
