Weight is certainly an important factor for many people, and part of the overall enjoyment of the instrument, but I don’t think that was the OP’s point.
The “weight?” question is thrown around on TB in almost in a discriminatory manner. Using it as the “opening question” above all other factors is a relatively recent phenomenon, and in my option spawned from this community and the likes of
sweetwater where specific wights are available for each piece. It hasn’t always been this way.
But there’s more to conform than weight… there’s also balance, relative body/neck length relationship, strap button position… even body shape.
And to put it into perspective… “back in the day” when basses were bought in store…. Weights were never provided (still aren’t), and probably won’t be written on the price tags any time soon.
When playing a bass in person/store, one usually thinks to themselves… does it play well, sound good, is it comfortable, light heavy…. One usually doesn’t say “hmmm this feels and sounds pretty great, it’s the perfect bass for me… and if it’s 9lbs15oz I’ll buy it, but it it’s 10lbs1oz I won’t.”
This is fully a recent and online phenomenon.
if your buying online without trying first… I get it…its certainly important (I didn’t buy a bass online because it was close to 11lbs and a a different short scale because it was 10lbs, I have a shoulder issue)… but it’s not the only factor when it comes to comfort… and so using “weight?” in this manner is probably a little over done.
That said, for classifieds here on TB, it’s becoming pretty standard, so might as well include it if one is putting in the effort to post anyway. But it’s not negative is someone doesn’t.
Also imagine “weight?” Was the first question you are asked when on a first date with someone you’ve never met before!? Lol.
