Bigsby tuning stability

JolietJake

Any tips on how to tame the B string on my Epihone Riviera? The B string is not returning to pitch if I use the Bigsby to bend down. All the other strings are fine and if I pull up on the Bigsby, it all goes back into tune. I'm guessing the string is sticking somewhere, but not sure how to solve it.

Thanks.

Is it sticking flat or sharp?

Sharp: nut, or possibly tuner post.

Flat: bridge saddle.

Thanks. It's sticking flat. I'm presuming some kind of lubrication would be necessary? Any recommendations? Anything to avoid?

Have a close look at the saddle groove - if it's a tune-o-matic type (especially far-east-made) they can develop a burr in the groove, usually on the vertical face, which snags the string. You need to carefully smooth it out with a needle file.

Lubricating will help too, I use a tiny spot of standard lithium-based car grease. Don't overdo it, not only will it make a mess it will also damp the tone. (Really!)
