Adjust tuners?

[rfclef]

I have an Epi EBO with the big cloverleaf tuners with the open gear on the back... I put new strings on it and the are not stying in tune. I do not know if it is the strings or the tuners. Is it possible to "adjust" the tuners? Tighten the screw in the middle of the big gear or something?

Gracias, compadres...

Hi.

There's a few reasons for the new strings not staying in tune and the backlash between the worm and the wheel is not one of them. While the worm can always drive the wheel, the opposite is rare with the single start worm threads used in machine heads.

The usual reason for the strings not stayin in tune is the lack of pre-stretching when installing new strings and the strings slipping in the machine head posts.

The first one is debated to death in another threads, so the strings slipping in the post can be remedied by wrapping the end of the string differently to the post. I like to bend the loose end to the opposite direction while others like to stick the end to the hole. Different strokes for different folks.

You might also want to inspect the "biting edge" of the slot for wear. If it's too rounded, ie. worn, the string will slip if there's not enough windings around the post.

Thanks Sam...

I had read a couple posts about stretching the strings being bad for them and could kill em, so I stretched a little, but not much...

Stretching new strings bad? I've been doing it for 40 years. One thing that gets neglected when installing new strings is to be sure the string is NOT twisted at the bridge when first bringing the string up to tune. I usually bring them almost up to the note and then back them off enough with enough slack so I can take any twists out at the bridge before retuning. 3 wraps around the post is usually enough and be sure they go downward toward the headstock.
