JP6 Bridge Question

[Rush]

I had to remove all strings today and do some tuneups to my JP6. Got the guitar all tuned up with new strings, but the bridge is slightly raised. Just curious what I need to adjust to get it back dead even with the cavity?

I swear I used to know how to do this, but it's been so long since I've had to take all the strings off I can't remember. This is a 2002 guitar that gets a good amount of use, and it rarely goes out of tune. Love it.

Sounds like you've put heavier gauge strings on, which puts more tension on the trem and raises it.

If so, you'll need to adjust the trem tension to compensate by screwing the trem claw in slightly (located behind the trem cavity cover on the back of the guitar).

Screw it in, but leave the trem still raised very slightly, as you'll now need to retune the guitar (all strings will be sharp).

After retuning, check the trem. If it still needs adjusting, repeat the above step. Obviously if you've gone too far and the trem is leaning back you need to let the trem claw out a little.

Your action has probably also changed, so you might need to tweak the truss rod too :

Note that if you've installed the SAME gauge strings, the neck might take a little time to settle after taking all the strings off, depending on how long you had them off (with no string tension on the neck, it'll bow back a bit) - this can also affect the trem level.

My bet is you've put heavier gauge strings on.

In the future, if you have to take all the strings off on your JP again to clean the fretboard etc.. Try placing something underneath the bridge so that it will stay parallel with the body. I've used just the right amount of post-its and slid it right underneath it to keep all the tension, and it works perfectly. This will make it easier for you to change the strings and clean the fretboard.

i would also add not to forget to re-check intonation. Heavier gauge will cause the saddles to move forward towards the neck, just make sure it is correct.

the thing is that having removed all strings i think you are in a position of having to adjust everything starting from the truss rod, to bridge, to intonation

You can remove all the strings at the same time as long as their is something suporting the bridge parallel with the body as if the strings were still holding it. I remove all of them each time I change my strings so I can clean the neck and there are no problems whatsoever, you just gotta remember to keep the post-its under the bridge.

Quick Tip: Dont remove the post-its (or w.e is holding the bridge up) until all the strings are back on and even tuned.

Thanks for all of the replies. The intonation is fine, and I'm still using the .10 slinkys that came with on the guitar. I should have blocked it, but I didn't think it would be a big deal. I did adjust the action and let it settle over night, but it's still slightly over the cavity. Other than that everything is fine.

So in that case, what do you think would be the most likely cause?
