Bridge is jacked after string change (lemmy.ca)

I changed the strings on my Jackson Dinky JS11. Normally I use light gauge, but this time I went with medium. After tuning it and noticing the difference in thickness, the bridge is on a sharp angle, and the whammy bar couldn't even swivel past the volume knob.

I tried loosening the two bridge screws which helped a bit and raised it to be less sharp of an angle, but it also raised the action considerably. At least the whammy bar can swivel freely. But the amount I can "wham" seems less than before, too. (Pictures are after this adjustment)

Is there a way to get the back end of the bridge downward so it is more "even"? That would reduce some of the action and give me more whammy room?

You need to rebalance your spring tension in the rear recess. Or just go back to the same gauge you had before.

[–] eezeebee@lemmy.ca 1 points 1 year ago (2 children)

I've just tried opening it up and tightening the screws attached to the spring mechanism to get it to pull back more. I don't see a noticeable difference on the bridge angle, though.

Sounds like this JS11 might not be designed to handle the higher gauge?

[–] wreel@lemmy.sdf.org 3 points 1 year ago (1 children)

I'd recommend going back to the previous gauge or getting it set up at a shop then. I don't feel comfortable recommending you cranking on the string retainer screws any more if you're not comfortable with it.

[–] eezeebee@lemmy.ca 2 points 1 year ago (1 children)

I've tightened them to the point they're practically flush so I can't go further. And yeah, tight springs are scary to begin with.

[–] DarkInspiration@lemmy.world 2 points 1 year ago (1 children)

Did you loose the tension on the strings as you were tightening the screws? Because that also matters in order to balance the tension

[–] eezeebee@lemmy.ca 1 points 1 year ago

I have now, after the fact. Still not much difference on the bridge angle.

[–] DarkInspiration@lemmy.world 2 points 1 year ago (1 children)

How many turns? You'll probably have to crank them quite a bit. And don't forget to loosen the strings!

[–] eezeebee@lemmy.ca 1 points 1 year ago

All the turns. They're as tight as they can go without stripping.

[–] DarkInspiration@lemmy.world 3 points 1 year ago (2 children)

Thicker strings mean higher tension, so you actually want to tighten the claw screws on the guitar's back in order to pull the bridge back down.

What do you mean by "I tried loosening the two bridge screws"? Could you clarify?

[–] eezeebee@lemmy.ca 1 points 1 year ago (3 children)

I figured it was the strings causing it. Here's a pic of the bridge screws I'm referring to. Thanks

[–] HamsterRage@lemmy.ca 3 points 1 year ago (2 children)

What gauge did you put on there? A wound G string!

[–] DarkInspiration@lemmy.world 2 points 1 year ago* (last edited 1 year ago) (1 children)

Shit that's right! I didn't even notice that!

@eezeebee you bought electric guitar strings, right?

[–] eezeebee@lemmy.ca 1 points 1 year ago

Honestly I've had these laying around for over a year. It's quite possible they were meant for my acoustic, but I don't remember. I seem to recall acoustic string packs saying so in the past. Also possible I'm an idiot (the evidence is mounting)

[–] eezeebee@lemmy.ca 1 points 1 year ago (1 children)

These. And yeah I found that odd, too. If this is medium I would hate to try heavy.

[–] DarkInspiration@lemmy.world 4 points 1 year ago (1 children)

It's medium, for jazz

13s on your dinky might be a little too much if you want to play on E standard.

Pretty decent if you want to play in C ou D Standard, though

[–] eezeebee@lemmy.ca 1 points 1 year ago (1 children)

I'm trying to play some death/doom metal type stuff. Should have mentioned this is tuned to D standard. Maybe I can get away with tuning lower to compensate though. Thank you

[–] DarkInspiration@lemmy.world 2 points 1 year ago

No problem!

[–] DarkInspiration@lemmy.world 2 points 1 year ago (1 children)

So.. Those are not the right screws to turn in that situation.. And that's why your action is super high.

I'd recommend you screw them down as they were before, not all the way down! Else the bridge won't be able to pivot.

[–] eezeebee@lemmy.ca 1 points 1 year ago

I'll try setting them back. Thanks so much for your help

[–] kiwifoxtrot@lemmy.world 2 points 1 year ago (1 children)

Those aren't the screws you need to tighten! You need to flip the guitar over, take the back plate off, and adjust the screws in the cavity. You should only adjust those with the string tension off. Send us a picture before you do anything.

[–] eezeebee@lemmy.ca 2 points 1 year ago* (last edited 1 year ago) (1 children)

Youtube told me they were, but yeah I agree they aren't correct for my problem. PS I loosened them because after putting on the new strings and tuning, the bridge was sharply pointed downward toward the pickups, almost digging into the body.

I did take off the back plate and tightened the two screws attached to the spring mechanism, as tight as they would go without stripping. That didn't make too much of a difference unfortunately.

[–] kiwifoxtrot@lemmy.world 2 points 1 year ago (1 children)

I'd change the gauge of the strings then.

[–] eezeebee@lemmy.ca 1 points 1 year ago

That seems like the root cause of this issue. I'll try downtuning and see if I can live with it that way before resorting to changing strings again. Thanks for your help

[–] eezeebee@lemmy.ca 1 points 1 year ago

I’ve just tried opening up the back panel and tightening the screws attached to the spring mechanism to get it to pull back more. I don’t see a noticeable difference on the bridge angle, though.

Just wanted to chime in since it seems like a few people miss that you put THIRTEENS on it.

Adjusting the claw in the back is what you do when you go from 9s to 10s. We've all had to do it which is why that was the advice you were given.

13s coming from 9s or 10s is EXTREME. I don't have the tension chart in front of me but that is a ton more tension Even at D standard.

Here's your fix; you need more springs. I didn't see a picture but I would guess your guitar (like most other trem equipped guitars) only has three springs. For most tunings and string combinations three springs are sufficient.

You are not most string combinations. You need five springs, that'll address your immediate concern.

However, I reckon you have a couple more issues whether you've noticed or not. Depending on how your nut is cut you can generally get away with going up a gauge in strings without too much issue. If your bridge is pulling up that much you've definitely gone up more than one string gauge. You're definitely going to need that nut cut for 13s if you even want a shot at intonation or tuning stability.

I'm sure it's also in major need of a truss rod adjustment.

Your best bet is to take it to a tech and have it set up. Especially now that you've fiddled with the bridge posts. This is the only way to ensure everything is adjusted correctly for the new string gauge. As general rule of thumb you can safely change strings up or down a gauge without too much consideration. Any more than that and the guitar is going to need a complete setup.

For what it's worth, once setup your guitar should play fine with 13s. I don't think you have any cause for concern in regards to the guitar being able to "handle" it.

However, adding a couple springs will solve your most immediate concern.

[–] eezeebee@lemmy.ca 1 points 1 year ago

Thanks, I'll look into more springs.

After fiddling with it a bit more it is playable and stays in tune, surprisingly enough. Action is a bit high for my liking, but I was getting 1st fret buzzing before changing strings and that's fixed now.

The nut for the truss rod appears to be stripped so I wasn't able to adjust that, unfortunately.
