I'll admit, I've become a bit of a weight snob. I'll also admit that TB made me that way, and before posting here a lot I never thought about weight at all.
Right now I have an 8 lbs Precision and an 8.5 lbs Jazz bass (with a lot of neck dive on the Jazz). I ONLY play in the studio, sitting down, and will never, EVER in my life gig. That being said, even lifting a bass of the stand, I enjoy them being light. It just feels nice - but that part doesn't matter much.
There is a bass I REALLY want: rare, beautiful, good price, but it's 9.5+ lbs. Everything about it is perfect, except the weight scares me.
Do you think weight of a bass matters at all when sitting down, or is weight only a concern with a strap standing up?
To be perfectly honest? I don't really concern myself with what a bass weighs. Unless it's as heavy - or heavier - than the 30+ lbs. of loaded-with-a-100-round-assault-pack M-60 machine gun. The one that I carried - on an assault sling - for more years than I care to think about. However...
I very seldom play anything while sitting down; when I do, it's almost always my '63 long scale, Type 3 ODE banjo. It just seems... easier... to play it that way. And, for some reason, I've never thought to try and find a strap for the thing. I have no idea how much it weighs - but, really; who cares? It's a frickin'
banjo...

I do occasionally play my Gibson-clone Eastwood "Flying Vee" bass while sitting down. If you position it just right, it works well that way. But, the weight (7.11 lbs.) isn't really a factor; nor is the fact that it's a little neck-heavy. So...
I don't really know what to tell you, except that;
1. IMO, for someone who's really concerned about the bass's weight? Yeah, it would most likely be more comfortable to play a "heavy" bass while sitting down. And doing it with a strap would probably make it even easier, too.
2. Out of the 22 basses I own, about 1/3 of them weigh about 9 lbs., plus or minus. The herd average is 7.2 lbs., but I have several
very light basses (small hollow body basses tend to be... rather light) that skew the average down a bit. The basses I usually reach for, though, tend to be in the 9-10 lb. range. So, bottom line?
I'd say - if you really want that "heavy" bass? Then buy the thing, and if sitting down to play it is what works best for you? Then play it sitting down. Don't worry about it; just enjoy the thing...
