@el murdoque -
In no way am I implying your reasons are wrong for you. They did get me thinking, though, about how they sit with my perspective. Different strokes and all that, right?
1. Jaco only needed four.
Jaco's dead. I don't base my choices on what some guy 40 years ago that I never met plays. Anthony Jackson only needs 6, as does John Patitucci. And had 6'ers been a thing instead of an anomaly in his heyday, who knows? He may have loved one.
2. Leo got it right the first time.
We don't drive Model T's anymore, because designs on cars have improved (not comparing a Fender to a T, but why should I be limited to what was created something like 70 years ago?) The fact that there's a demand for more than 4 strings tells me Leo maybe didn't consider everything.
3. String choice is quite limited and changing strings is EXPENSIVE.
When you find the strings you like, it's not a problem. The extra 10 bucks isn't a deal-killer for me. I can always find DR Sunbeam 6'ers.
4. When you do your own setup, those six string necks are a test of patience. Either you have dual trussrods (which is scary), or you have a reinforced neck with single rod, but in any case, do a quarter turn, tune the bass and go on holidays for two weeks, the neck takes ages to set.
I have my dual-truss 6's set up quite quickly and easily. Do it twice a year, and never takes more than a day, if that.
5. Muting. Going from four to five feels like you need to wrap your brain around the fact that there's one more string now and once you got that into muscle memory, you're good to go. On a six, you can take the muting technique you learned on a 4 and toss it in the bin, re-learning right hand technique from square one.
Not hard, once you get it. Coming from a 5 made it easy. i don't even have to think about it.
6. Note choice. More often than not, you have the choice of playing that note by going one string lower (fatter) and five frets up or going one string down (skinnier) and five frets down. You need to make up your mind, because that fretboard buries you in options.
Not really, whatever's best just comes naturally, once you've done it long enough. I might think about that when I'm figuring out a tune, but it never comes up when I'm actually in the thick of it.
7. Weight. You think 9lbs is heavy for a bass? Go get a gym membership ASAP!
My Wal 5 string is almost 11 pounds, my EBMM is 10. My Bordwell fretless 6 is 9.5. I'm just used to heavy basses.
8. Cost. Buying a six will naturally set you back further than buying the same bass with less strings.
Depends on what one's budget is. I generally play customs, so I'm shelling out 3k+ no matter what I'm getting, but there are certainly affordable 6'ers. I started on a 6 string Hohner that I picked up for 450 bucks.
9. Learning the notes on that fretboard takes much longer because there are more strings.
Nah.
10. Intimidation. When you are in an audition, the guitarist will take a step back when you pull out a bass that has as many strings as their axe's got and they fear for their guitar's precious sonic personal space being invaded by a much bigger guitar, so they will much rather go with the other guy who brought a Fender P bass.
That's about knowing when to use the right tool. If I were playing in some classic rock/dadband situation, I wouldn't show up with a 6, I'd bring a 5. A jazz band or some other type of situation, generally the musicians are not gonna be intimidated. I don't play with insecure guitarists who would get uptight about that kinda stuff. I
avoid guitarists like that like the plague.
11. Noodling. I mean just because you can does not mean you will, but having the option to go up two octaves and play a quick fill whenever you feel like it (or whenever there's room) certainly invites doing so.
That's what good musicianship is all about... knowing when not to noodle. There are no shortage of 4 string wankers.
These are my personal top reasons I could never be talked out of playing a 6.
