Bass shim size

Just use a piece of business card, 1/2 inch wide. Try, and add another if it needs more. If you take you bass to an expensive shop, they will use business card as well, it's pretty much standard among repair folks.

That. Having agreed with “this” and “that”, yo want a shim about .01” thick at the fat end.

Stewmac shims are pretty steep but it’s your money.

You could use the business card method first and measure the angles and order the right shim if you really want to use one.

 

Stationary rosewood bridge? More info/pics.

 

Like the others have said, use a small cut piece of business card in the pocket against the wall. If you consider the stew-Mac shim they will scare you in buying their product. Don’t fall for the “ski jump” thing.

 

Can you take a picture of where you're placing the shim? It should be right at the back of the neck pocket, under the end of the neck closest to the body.

 

The idea of a shim is to change the neck angle. You want to move the head of the bass back relative to the plane of the body. So you shim the part of the pocket furthest into the body, If you shim the entire pocket you just change the height of the neck.

 

Generally that will indicate uneven frets. Or a ski jump at the heel. Don’t try to fix it with relief adjustment: won’t work that high. You can self diagnose with a credit card and span 3 fets looking for any rocking over a high fret. Temporarily you will have to raise your action. Long term fix is fret level and dressing.

 

The shim isn’t causing it. You can’t put a shim under the saddle to raise action? The saddle is glued in place?

 

We never have seen any pictures of this. What are you working on, specifically, and could you post some pictures? Curiosity is killing me. So far, it’s a bolt on neck and a completely unadjustable bridge...

 

Hmm. $4.81. Free shipping. Maybe you should press the buy it now button.
