| Buying a 4-string set and adding the B and C is an option indeed, thanks for pointing out.
As for the D-tuning: my band tunes down 2 steps and most songs are written in D. It is much easier for me to have an 'open' D as well for some of the riffs, but I also like the option of going lower then that D every now and then, so tuning the B up to D is not an option. Also, I like the choice of being able to play the D on the fifth position of the B string (A, in my case), it's convenient for some riffs. |
