Looking around on Reverb and other (local) used stuff sites, i see a lot of basses with the necks removed to show whats underneath. I'm a technician and also a pretty curious guy... but this always rustles my jimmies. A lot of basses have what is called a "bolt-on" construction. In fact no bolt ever comes near it (wish they did). It is "screwed on" and everyone who ever used screws knows that it's in some way a destructive process. As a screw is turned in, the "thread" is being cut. This is not neat and nice thread like when a bolt is used, but crude and actually different for each screw. It's a very secure connection and solid and ridgid etc, but when you loosen the screws to remove the neck, you can, in some cases, see wood come out of the hole. meaning, the next time you reinstall it, the screws will have lost some power, tightening wise. worst thing that can happen is not the same screw in the same hole. No screw is exactly the same as an other one. I know i'm a Nitpick right now, but i've been thinking about this for quite a while and find myself looking at awesome J-Basses that are and look great, but i hit the little cross as soon as i see a picture with the neck removed or a clearly damaged neck-joint. Am i alone in this? am i going too far with it? Should i go to therapy?
