Makes no difference. I go between the neck joint, pickup and bridge with no neck dive because my hand is ON THE BASS.
the "varying pressure" doesn't do jack. Why do you need to overcomplicate things?
When I play slap, with a divey bass, the pressure from my right arm is less, the neck wants to dive, and I have to hold the bass up with my left hand.
If you think I'm overcomplicating things - what is the simple solution you had in mind?
