Shims: The lazy mans fix??

Hey, so, shims.. Heard this one too many times?

I currently have a shimmed p bass neck, done by a past
luthier with a slather of maple, or similar wood, cut to your
average type of shim size, placed at the heel end - usual deal
to remedy bottomed out saddles.

Here's the triple whammy: When I remove the shim, the
sustain is greater and the bass feels and sounds more
"whole". The neck seems to have developed a slight bend at
the heel, which I believe is from the shim (over 9 years) but
it may not be. And lastly, I have sanded out a neck pocket on
a six string elec guitar before and it was slow, careful work,
but not super hard, and it didn't take much sanding (block +
sand paper).

I plan on sanding the neck pocket on this p bass, to get back
the good that the shim takes away. Anyone wanna talk me
out of it?

The benefits I CAN see with shims are: easy, fast fix, and no
permanent potential muck ups (apart from eventual neck
bend at heel) BUT, I think shims are a lazy, tone sucking fix.

Thoughts/feelings??


As usual, some pics would help. Secondly, how wide is your shim? I'm thinking a w-i-d-e-r shim would maybe remedy the tone you say it's "sucking outta the bass". Common sense tells me a w-i-d-e-r shim equals more wood in contact with the neck in the neck pocket. I'm no Carl Thompson, or Vinny Fodera, but, common sense seems to be right most of the time. Just my 2 cents......
 
Have you tried it? It's easy and virtually free so there's no real impediments to trying it. You can always try something else if it doesn't work in your case.

We might have been talking about two different things when referring to "ski-jump", sounds like.

I'm talking about an unwanted warp in the fingerboard when I use the term - a shim is an orthogonal treatment for that problem.

But for correcting a tilt or adjusting the height of the board compared to the rest of the bass, there shimming is an applicable fix.

Like I said, I have shims on both my bolt-neck basses now to correct too-low fingerboards on both. My jazz bass is a defret project and required a full-pocket shim to get the fingerboard back up to a usable height. It didn't require any further adjustment tho since the neck alignment was already fine. So it's just a flat shim. My L2K is sitting on the neck jig right now waiting on parts and tools. That job will be to finally level the fingerboard which was goofed up from new. I'm also going to flatten the radius out to 9.5". It has a shim in it for the same reason as the jazz, the fingerboard has always been too low on it from the start. And after reradiusing and levelling, enough wood might come off to lower it even more. So the shim.....

So yes I'm definitely a shim user (but only for applicable fixes).

We aren't...give it a try next time you have one, it couldn't hurt.

If indeed you _are_ referring to an unwanted relief in the neck:
- yes it could hurt. Chasing a problem with the wrong fix is not a good use of time and effort. It can also lead to expensive additional damage on top of what's already wrong with the guitar/bass.
- it's the wrong fix, regardless of what you think (simply asserting over and over that it's a proper fix doesn't make it true).
- if you do think this is a correct fix for a warped fingerboard, the likelihood is very high that you've learnt other aspects of guitar maint/repair incorrectly as well. So we can't trust other items you might suggest about correcting problems because of that and we can simply disregard them.

Soon, I may try it on a friend's Telecaster guitar that he says is a bit "jumpy"

If I knew who your friend was, I would caution them to not give you any money for your work. And for him/her to take it to someone who does know what they're doing. I just hope the guitar survives the ordeal and eventually gets fixed correctly.

It never has. Don't be afraid. Fear is the mind-killer.

- it's the wrong fix, regardless of what you think (simply asserting over and over that it's a proper fix doesn't make it true).

Nonsense. You simply saying it isn't right doesn't change my success with the method.

- if you do think this is a correct fix for a warped fingerboard, the likelihood is very high that you've learnt other aspects of guitar maint/repair incorrectly as well. So we can't trust other items you might suggest about correcting problems because of that and we can simply disregard them.

LOL. I couldn't care less what you disregard. However, since you have no experience with the method, I guess we can all safely disregard your remarks about it.

If I knew who your friend was, I would caution them to not give you any money for your work. And for him/her to take it to someone who does know what they're doing. I just hope the guitar survives the ordeal and eventually gets fixed correctly.

LOL...again. Then you should be happy to know that I don't charge my friends for minor work such as this...(waiting for it...) And your attack says much more about you that it does about me.

I triple dog dare you to try it.

;)
