A 4" width leather strap has always neutralized the problem completely for me (at least on stage and on my feet). The added benefit is that distributing the weight does away with all (or at least 90%) of the fatigue associated with multiple, long sets + and 11lb plus instrument.
Come to think of it -- Who do those basses think they are?!? We gotta show them who's boss!!! (Now I feel better - LOL)![]()
I am with you bassman, I don't really love a heavy guitar on my shoulder all night, but with the good strap, I never seem to notice. ( I have 2 Jacksons in the 15lb category )
For me, my 8lb 5 string bass makes the neck move all over the place, and I hate that it, plus my days of swinging the thing around my head stopped when I bought something worth more than a couple hundred bucks..
and show your bass who's the boss? ?? that's pretty apparent the very minute you plug it into the amp, and beat on the strings...

you ever hear a guitar NOT cry when you smack the strings really hard?... It's the high quality guitars that can actually TAKE the punishment for 20 years, and still look like it did when you bought it.
my closing point for the topic of the thread is, if you have issues with ANY guitar that you don't like due to the way you have to "comfortably" wear it, and because of that it dives, you have 2 choices naturally ---- find something that you like better and sell the neckdiver, or suffer with the awesome bass you already have.
