Thought experiment here. What if the standard tuning for a 4-string bass was D-G-C-F. All strings tuned two half-steps down. I think that could be a good mix between the standard EADG which many may feel doesn't go low enough, and 5-string bass which goes low but adds another string.
I realize that TB is full of traditional people too, but if you let your mind open up and just go with this idea for a minute...
What would the drawbacks to this be? Relearn the fretboard, low tension strings (or new gauges), freak you out if you play guitar too, hard to double/follow riffs in E or what do you think?
What would the pros be? 4-string with kind of extended range.(Takes away the two very highest notes but, probably not a big deal) . Can still play a 4-string which you're comfortable with, even if you need the low D and Eb often?
Eliminate the need for a hipshot d-tuner.
I got this idea while playing in a cover band and "needing" to get that low D on some songs. With the new tuning I'd get the low Eb as a bonus. I feel that the low D is quite normal now in a lot of music. People are used to hearing that low of a bassnote, and it sits nicely in a mix. The norm is jump a 7th from low E to the open string D, like they did always/most of the time earlier. That may not always sound great.
If I was starting out on bass now, playing a 4-string bass, I might have wanted to go with D-G-C-F tuning. In fact if I did switch today, it would probably not take more than a couple of months getting used to it. Alas, I play both bass and guitar in my band (we switch instruments for fun), and have both a few 4's and a 5-string bass, so I am not seeing it in my immediate future, for fear of total confusion, but I think I may be on to something. What are your thoughts?
