Local guitar expert filled the saddles but the strings still break

Exactly what Ernie Ball strings are you using and how is it strung? Through body, through bridge, or top load?

 

I use Ernie Ball strings on every bass I own, and I've never broken one. I've used several different gauges and varieties, as well as top load and through body configurations, too. Something else is afoot.

 

Time for some pics of issue...or if you posted pics already then a re-direct..

 

Where do they break?

 

My next suspect is die cast saddles; time for new ones?

 

A most important question. If it's breaking at the saddle, perhaps a few swipes with a nut file will create a smooth bed for the string to sit in.

 

Been there; done that.

 

Are you a heavy handed player? I'm just trying to get an idea. Pick player? The saddles in the pics look pretty good, and the fact you have taken it to a tech I'm assuming that knows what he is doing should have taken care of that issue.

I know when I use a pick I seem to put more force on the strings, and I'm a heavy handed player to get the sound out of the strings.

Do you have other basses and if so do you break strings? Another thought would be trying a heavier gauge string as well.

Sorry I can't be more help. Good luck with everything.

 

Based on that info I'd look at replacing the bridge inserts. They might have had the break angles messed up a bit, or just worn down from use. The bridge has wear on it, so that could be an issue. As sissy Kathy said, start looking at replacing those bridge inserts where the strings rest.

Btw, I'm a very heavy handed player, and I've only broken one string in my career, and it was simply due to a string being completely worn out.

 

From those pics I see string wind ridges in the saddle. Should not see them if it’s just been filed. What’s up with those ridges in the bottom of the saddle?

 

They’re rough spots. They cause undue string movement when you play, right at the spot the string is bent. Vibration allowed at a bend in steel causes breakage.

Also, that kind of wear indicates to me you aren’t setting witness points and the strings aren’t breaking hard over the saddles but are left to loosely arc over the saddles so they flop around in there wearing grooves in the saddles and stressing the string cores.

My question is how they are there after a so proclaimed pro supposedly filed the saddles? Poor job.

 

They're die cast saddles and don't dress very well. Stop messing with them and order new saddles. You need two narrow and two wide saddles. Here's Warwick's site that has them.

As long as you are playing with a heavy hand and using zinc saddles be prepared to do this on a regular basis. I'd play with a lighter touch and let the amp do the work, that's what it's there for.

 

True that Sissykathy, zinc is very difficult to file.

Yep get new saddles. Order two sets so you have spares.

 

I'd replace the saddles and see what effect that has. As for playing heavy handed...do you like the sound your bass makes? If you do, then being "heavy handed" is a part of that, and I suggest you not change a thing with respect to that.

I tend to play with a fairly soft touch, but in the past year, I have found the benefits thing I formerly considered "bad" - playing hard, using a pick, and fret buzz - have on my tone.
