Shimming a p bass

[Stub Mandrel]

A ski jump is the endof the neck turning up a little, as we all know.

 

On a typical 19 or 20 fret neck the attachment screws are about 3 frets apart.

 

Any bending force would be due to the screws between the shim and the screws at the other end.

 

If you are worried, rather than worrying about wedges, just make your shim long enough that the screws penetrate it. The neck is then under no bending force.

I had a 1963 P Bass that had had a wee shim fitted. There was no hint of end of the fretboard turning up and heaven knows how long that shim had been in there.
