But what I meant wasn't only the neck bending tension ... There will also be very high shear tension on the neck joint with the body wether it's neck-thru or bolt-on .
I read that Slash broke his neck before during a jam while he was bending it forward ... He was injured badly too... I think that strings with that gauge in standard tuning probably have more tension than Slash's bending the neck.
This guy must have his neck supported with cast steel or something !
