How light is too light? (Neck dive)

[yodedude2]

yes, but remember--neck dive is greatly affected by the instrument's center of gravity*. that's why i suggested a brass bridge instead of the heavier pickup. you must counterbalance the headstock. the other majorly important determinants are the fulcrum points for the strap.

*along the x-axis, if that makes sense. you want to shift weight toward the butt and away from the head. insert your own joke here.

Warmoth necks with steel reinforcement bars tend to be really heavy. But now I believe Warmoth makes some necks with graphite reinforcement bars, which are much lighter.

Their short scale necks have no reinforcement bars at all.

"Stiffening rods are not necessary in SSB Warhead and SSB Tiltback necks due to their shortened scale."

Edit: Damnit, you beat me to it.

How light is too light? If it has no effect on your stiffening rod, it's too light.

I had a neck-diving J that I fixed by moving the strap buttons. First I put the horn button on the back of the horn where it served as a pivot. The bass would not dive when suspended from this point. Then I moved the bridge button 2 3/16" toward the floor. What this did was allow the strap to cross the body in the back. In other words, I had some of the body weight hanging outboard of the bridge button. I took this pic at roughly the angle I hung it off my body.

Right- that moves the (vertical) centerline between the strap buttons forward, countering the neck/headstock weight vs a higher rear strap pin that moves the centerline back.

Good illustration.

The single pivot at CG on the Steinberger L-2 was the best arrangement ever for prevention of neck dive.

It was good for the back, too. The Fender Go-Around Waist Belt was even better for the back. It put the weight on the hips.
