Jem BSB cant lower the strings any further

Hi ,I have a jem BSB and cant get the action very low..Was thinking of shortening the tremelo height rods so I could create some space to lower some more.Is this a bad idea?If so , why?

Thanks but that doesn't address my question as far as I can see.

For the record I'm not a pro tech... Just a player with a lot of years of experience...

But my understanding is that if your trem studs are maxed out as low as they can go and your action is still too high you will need to shim your neck. If your trem studs wont go any lower that means they are bottomed out on the body, so shortening them won't change anything.

This is not really an unusual scenario. I had to do this with my Jem 7VSBL to get the action where I wanted it. But now its absolutely perfect! I did not do it myself though, I had a pro do it for me.

Best of luck!

Re: Jem BSB cant lower the strings any further

Thanks kfssdude.The studs sit in a metal casing , so reducing the length of the stud would mean it could go deeper into the metal casing thus giving a lower point of contact with the tremelo.Thats how I see it .Maybe I'm missing something.I have heard of shimming the neck but was wondering if my idea would work.

Shimming the neck is easier, as it's nondestructive.
Your idea requires drilling the holes a bit deeper.

Re: Jem BSB cant lower the strings any further

Well the studs do screw down into the threaded metal "sockets" (unsure of the proper term) which are set into the body. However, from taking them apart on several guitars it has been my experience that when they are bottomed out it is not due to the stud being at the bottom of the shaft, but because the flanged head (into which the trem's knife edges fit) is flush against the top of the body. Yours may be different but that was the case with my 7VSBL.

Regardless, there are other factors to consider. If you were to modify the studs as you suggested, you would be sinking the trem deeper into its cavity... Are you going to run into problems there? In other words, if you trem is that low in the trem cavity, will you still have a full range of motion without hitting or rubbing the body? Also, as you sink the trem your action does lower, but so does the angle of the strings relative to the neck. If you get a very low action using the method you suggested, without a neck shim, it sounds as though you may have moved the trem out of its relatively parallel string position and as a result may run into significant fret buzz issues.

Again... I'm not a pro tech but these are the things I have run into in my experience that might be worth considering...

Yeah, it's a bad idea. the shorter the length of the studs-the less stable they'll be in the anchor.

I think the OP needs to loosen and back off the stud locks before doing anything else.

$100 says his locks are bottoming out............

Good call. Didn't even think about if he had stud locks....

Yes, it may "work", but it's a bad idea. Shimming a neck is a common remedy for the issue you describe, is reversible, and (as noted above) is non destructive. Any tech worth his salt -- heck, worth half his salt -- should be able to do this very easily.

As well (also noted above) check that your stud locks haven't bottomed out.

I have three JEMs that have the neck shim fix to elevate the neck from thebody.

Re: Jem BSB cant lower the strings any further

Thanks for all the replies.Well I had a look at it was in fact the stud locks preventing the me lowering it even further .I backed off the locks a little a now have a lower action.I'm guessing this is also a bad idea and I should just get a shim ??

No not a bad idea, but you need to lock them back down when you're done setting the trem height. If you use the bar a lot with the studs unlocked it will wiggle the anchors loose in the body.
