Default Cracked bridge on my Eastman

I was tuning up my 2019 Eastman E20P a couple weeks ago and heard a little "pop." Same thing happened a few days later. And then yesterday I noticed that the bridge had cracked. Not good, as you can see by the photos. There is a crack that radiates along the grain lines from each end of the saddle slot. And the saddle is starting to lean a bit.

I talked to a luthier on the phone and sent him the two photos I've posted here. He said that it needs to have the bridge replaced. He's willing to do the work. Said he'll probably have to make the new bridge slightly bigger to cover any damage he might cause removing this bridge. I didn't like the sound of that, but I can see where it could happen. We talked about gluing it, but he thinks the crack is beyond that, and I tend to agree.

I also checked with an Eastman dealer down in Denver who said that the warranty only covers the original purchaser. Too bad for me, I bought it used. But I like this little guitar so much that I'm willing to spend the money to have it put right.

Am I missing anything? Any other options?

Bad news. I also have a 2019 E20-P but we donlt get much of warranties here in the UK from foreign made instruments.

Two possible remedies :

1. as your luthier says,

2. "microsurgery" - glue into cracks and clamp until firm.
I'd suggest a luthier job though.

Find a repairman who is competent. An oversize bridge is unacceptable.

A good luthier should be able to remove that bridge with zero "damage." The bridge will need to be replaced. I've never had success repairing that type of crack with glue. Forward pressure from the saddle under string tension usually breaks it again.

Just thinking out loud here, but I wonder if it would be possible to contact Eastman and see if you can buy a replacement bridge from them so you can keep the factory look? You'd still need a luthier to replace it, but when he/she was done, you'd never be able to tell it happened.

Question: How is a bridge removed? Pried from the top, pushed off from underneath? What tools are used?

Your luthier is talking about a pencil line increase in the footprint of a new bridge. Not enough to make a significant difference that you might actually be able to hear. Making a duplicate bridge, indistinguishable from the original, is not hard. I agree glueing is not a good option. If you haven’t already taken the tension off loosen the strings now.

BradHall, that's what he said. Less that 1/16".

And I got to thinking that the ebony above the crack is about to fall off on its own and should be easy to remove. Once it is gone, he will have that vacated space to work from if it is prying that needs to be done. (Does that make sense?) And if he leaves a small pry mark or two, it won't matter in the end.

And I have loosened the strings. Thanks.


jklotz- that's a good idea. I'll see what I can do.

Bridge is likely repairable without removing it. Neither oversize bridge nor the expectation of damage from removal is acceptable.

Loosen strings fully if you haven't already. Find a different "luthier."

Bridge is removed by heating the bridge from the top to soften the glue underneath, then removed gently with thin pallet knives...not pried. Once the glue is soft enough the pallet knife slides underneath easily to separate the glue joint.

Good to know, Bryan, thank you.

I wondered if heat might be involved.

KenL:

If you want to see it done, look at some videos of Rosa String Works on YouTube. Jerry replaces lots of bridges, so you’ll get a good idea of how it’s done. And he always manages to use the same bridge footprint.

HTH!

Thanks, Carol, good advice. Very informative.
