Epi Casino Chinese 2014 G string loss of tuning after string bending.

Recommended Posts

Hi

 

I have an Epi Casino, VS, Chinese 2014.

 

It's had a few mods by myself and luthier, TUSQ Nut, Graphite StringSaver saddles on stock bridge, Creamery PU's, rewire, CrazyParts Area 57 True Vintage taper pots, PIO caps, Switchcraft long throw switch and jack.

 

But I kept the Kluson style oval nickel tuners.

 

D'Addario EHR310 Half Rounds, Regular Light, 10-46 strings. Couple of months old.

 

Problem I have is the G string keeps going a little out of tune after a sting bend.

 

I've searched the forums and advice has usually been replace nut and saddles before changing tuners. Both are done already.

 

So is this a tuner problem do you think?

 

I've looked at Gotoh SD90's with nickel oval heads, Grover Small Button and I've read of Wilkinson & Kluson. If tuners need replacing, it's a gigging guitar, what's considered the better tuner option, or are they all those mentioned perfectly reliable.

 

I'm guessing original 1960's Casino's had Kluson ovals? And anyone know why so many supposedly genuine tuners for sale have no logo or name on them?

most often, it's the nut lost.

 

Try a dab of Vaseline in the nut slot for the string you're having troubles with. that should be enough to tell you if the nut is binding up on you.

Grover Vintage style 133N are drop in replacements, $40 at amazon. If you think you have tuner issues this could be the way to go. I have pictures on another casino thread (they don't change the look). I have a coupe but the tuners are the same on Chinese casinos. Let us know how it goes.

It can also be a result of excess string wraps around the tuning peg,

 

 

It could also be that your strings are "a couple of months old."

 

Lube up your nut [tongue] and change your strings already!

This ^^^^^^. My Grover Deluxe tuners on my Epi ES339 are good solid performers. I've heard of several owners having issues with Epiphone's newer spec no-name tuners.

I'm thinking it's one of these two issues. You can also use some powdered graphite in the nut slot for lube as well.

Is it going sharp or flat? If it's sharp, it's not the tuner - it's the nut. If it's going flat, then look at the tuner, or how you're wrapping the string on the post.

 

 

This is how I've been doing it for both acoustics and electrics and all my guitars stay stable through just about anything:

Thanks for the replies. So I mentioned I have a TUSQ nut, PTFE coated, to let the strings slide and not snag. So how many are lubing TUSQ nuts?

 

@flyingarmadillo, it's going flat and only the g string, all others are fine. The strings that are on were put on by the luthier as part of the setup after I made the hardware changes.

 

@kensh999, thanks for the tuner suggestion, I'd been looking at those or possibly Klusons.

 

@steve112 thanks. I'll have look at the Grover options.

 

@Parabar, thanks for the suggestion, strings are cleanly wrapped with excess length cut off so on this occasion I think not the problem but one to keep in mind.

 

I think I'll try tightening the tuner shaft, if that doesn't do it then I'll change the tuners and strings. Small cost on top of what I've changed already.

An old string is an old string. Doesn't matter who put it on the guitar. Before buying brand new tuners, just put on a new set of strings!

I just want to add that I have reported exactly this elsewhere on the board.

 

In my case it was on a brand new 2015 Gibson ES-339. So the strings were originals as fitted at Memphis.

It seems that this is a very common problem and that nut sauce and/or nut slot relief is the usual solution.

 

I think that the headstock designs are responsible. Both Epi & Gibson headstocks have kinks in the string path. This is most pronounced for the D & G strings where the kink angle is greatest. Since we are most likely to bend the G, this is where the binding & slippage typically occurs.
