Stingray 5 - choose your flavor, be it H HH HS, Classic, whatever.
Regarding how your B string sounds - if I judged my Reggie Hamilton CS5 based on how the B sounded when I played it for the first time I would have moved it on straight away. This base left the factory with Stainless strings, and the B was taper wound. When I put one of these back on it (sadowsky Blues)....massive improvement. Set up. no matter how good I think I am at it...the best Luthier local to me is a crap load better than I am....massive improvement. And thirdly, if you are judging how a B string sounds playing in your bedroom or a snotty little room in Music shop or whatever - you are kidding yourself if you think you KNOW how it sounds.
Most times if I A/B my SR5 and Reggie I will say to myself the SR is better. get the Reggie at a gig in a reasonable sized room and I slap myself around the head for even thinking it. To top it off - when the sound engineer comes up to me after I have played a set with each bass and says: Play the Reggie for the rest of the night! It becomes clear that what I hear 5' feet from my amp in my little rehearsal room means nothing. It is what happens in a big room out the front that really counts. A B string's tone doesn't focus in 5 or 10 feet, it's more like 15 or 20+.
The fact of the matter is, 99.5% of the time I play this bass, it is at home in my room. If a bass doesn't meet my standards when I'm sitting alone in my bedroom, I'm not going to consider it gig worthy.
Gigging and playing bass professionally may very well be something for me in the future, but it's not something I do right now. Right now, I just play for personal enjoyment. I want a bass that I will enjoy playing.
The bass I currently own is the only bass I've ever owned (though, I have only been playing for about 2 years). It is a fantastic bass in regards to playability and comfort. It looks pretty nice too. It's sound is pretty mediocre, but that's mainly due to the pickups and preamp, things that are pretty easily replaced.
My problem with my bass is the low B string. Every other string on this bass plays great, no rattling, no buzz, no unwanted noise. The B actually isn't too bad either, but I have to play it completely different than every other string to make it sound good. I have to feather it, I have to play it at the correct angle, I have to play it at the right place on the string. Why? Why do I have to give special attention to this string to prevent rattling when I don't have to with any of the other strings?
I've tried multiple strings, tapered and non-tapered and of various gauges and to some extent, they all rattle. It's not just while fretting an note, either. The biggest problem is how much it rattles when I play an open string.
It is because of all this that I have often seriously questioned the need for a 5-string bass. If the B is just going to suck, why get 5 strings? At times I've even questioned the need for anything below standard tuning.
But my time on talk bass has taught me a few things. People have made a lot of good points about the advantages of having that low B string. So I've persevered.
Thank you for the suggestions so far, everyone. The overwhelming response seems to be that Ernie Ball Music Man basses have excellent Low B strings, I may have to give them another try.
After reading this thread though, I've decided to do something. Next week I plan on taking my bass over to my local tech and explaining how I feel about my bass and its inadequacies regarding the low B and seeing what he can do about it, we'll see where that goes.
