I’m going to apply my experience shimming door hinges here and see if the logic transfers to shimming a bass neck.
In commercial jobs I sometimes install steel door and steel door frames. You screw the hinges to the door and then screw the hinges to the door frame. I then close the door and look at the gap between the door and the door frame (the reveal).
If the reveal between the door and frame to too tight I will shim the door hinge. I’ll place a small strip of cardboard (usually the manufacturer provides these strips in the hinge box) at the back of the hinge and then tighten down the screws.
The shim at the back creates a wedge and the barrel of the door then pivots away from the strike side (the side with the handle) of the frame. This increases the gap between the door and the frame. I’m using a shim to create a ‘see-saw’ effect and move the pivot point of the door hinge.
So far, so dull.
But If i apply this experience to only shimming part of the neck pocket I think the same thing will happen.
If the neck is currently parallel to the body of the guitar If I place a partial shim at the base of the neck pocket and then tighten the screws will I not tilt the head stock of the neck away from the parallel plane of the body.
If this is what I want to achieve then good. But if not then I don’t see why I wouldn’t shim the whole neck pocket to keep the neck parallel with the body of the bass.
Does my logic hold up @mpops1990 ?
