LP epiphone 100 "g" string problem,

Good question, tuners can be simple and some are complicated
a basic automatic guitar tuner you would not have to do anything to the settings, just tune normal on the E string then slowly down tune to D most tuners are a little sensitive, so go slow
and one thing I always do is go lower than the note I'm tuning to then tune up tell it's correct, strings seem to stay in tune better
Hope this helps ?
and if you have time check back on my profile
I will be doing some video tips this weekend
showing tuning, and some basic guitar repairs
thanks for your time

Most likely the bidge needs to be setup. Take it to any guitar shop to get it done.

The first thing to remember is that the strings will stretch so i always over tune it about a turn for small strings and 3 for the big strings. To prevent it from slipping when you are tightening the string pull it tight while turning it and make sure the string has overlapped its self a couple times before releasing it.

Here is a link to their standard manual:http://www.epiphone.com/images/EpiOwnrsManul.pdf Pay attention to Intonation and Saddle Adjustment for a Tune-O-matic bridge. They come adjusted but you may have to adjust if you change the guage of your strings.

Sounds like a warped neck, if the bridge isn't low what else would cause the strings to buzz.? With the gain problem perhaps the neck is twisted as
well as bowed. Epiphone are proving to be quite popular but they are built to a price and for beginners they are usually a good choice. Unfortunately some fakes of different guitars are sold on ebay and they often make better tennis rackets than a musical instrument. Unless you changed them the guitar usually has a cheaper Humbucker pickup. Check it's fitting anf make sure there are no loose parts or wiring sitting against the soundboard on the inside.

Try looking down the neck of the guitar and seeif you notice any warp or bend. Overtightening the strings can cause the opposite warp and the strings end up further from the frets. Also try some measuring. The distance between the any string and the fretboard starting at the nut and working down to the bottom of the fretboard. These measurements should be consistant
Also, check the nut to see if the grooves aren't too deep. This could cause buzzing by allowing less distance between the string and the first fret.

Make sure all the frets are seated correctly and not slightly out of kilter at one end.

That should give you enough to keep you busy for a while. There are plenty of reasoins why a string will buzz. I've covered a few mecanical ones but without sounding rude there are also player caused buzz. Depressing the string too far behind the fret can cause it whereas too close to the fret can kill the note. But that's not my field in this situation. Check all the above and then try your fingering. One way or the other that buzz will stop. The best way to check if it's you is to get someone else to try your guitar out and see if the buzz buzzes off :-)

good luck

the closer to the strings the greater the magnetic pull. it's a personal variable to the player.basically how aggresive of a sound you want

That's the problem; you're using light gauge guitar strings. Chances are that if you are not used to playing strings that light, you're fretting hand will hit the strings with more force than is neccesary to fret them, thereby forcing them out of tune. You can solve this problem by adding more winds around the string post (three or more winds should do it), or you can switch to a heavier gauge of string.

If they're true locking tuners, they should have a notch on the back of the gear housing that you turn with a nickel to engage the locking mechanism once tuning has been established.

Also; check the intonation of the guitar itself on an electronic tuner. If it tunes right but sounds out of tune when played, this is an intonation issue, and can be solved by adjusting a small set screw that moves the individual saddle back and forth in the tune-o-matic style bridge. You can check this by tuning the string to the correct note, then playing the same string at the 12th fret and checking it against your tuner. If it rings in true, you're fine, if it comes up flat or sharp, every note on the fretboard is going to be off by that much, and you'll have to adjust accordingly (turn the screw to the right to add length and lower a sharp note, turn the screw to the left to subtract length and raise a flat note, if I remember right).

Hope that helps.

hi there .... flat means does the string go lower in pitch ...needing the string to be tightend after you have bent it ?
Do you give the strings a real good pull a few times after fitting? this often corrects the problem .... let me know ..as there could be a few other reasons
cheers Pete

First, I don't know how long you've been playing guitar but you need to make sure the strings aren't old and/or not kept clean. The oils and skin cells from our fingers will cause strings to break down in there elasticity, therefore causing them to lose there retention (eg. memory). If you have a locking system with floating bridge then make sure your locks are tight, but not to tight as to strip or break the screws. Next, if you have a cheaper guitar, like in the $250 range, you will experience this more often than not, especially if you don't have a locking system. But just remember that guitars have to be retuned all the time (just watch live video of guitarists like Jimmy Page and Angus Young, etc.) if you play a lot and really play the instrument to the fullest (eg. Dive Bombs, EVH Horsie, Pitch Bends, etc.). Also, when you put on new strings they need time to stretch before they find that place where they retain their memory so it's a good idea to play and stretch the strings using various techniques like bending and whammy (EVH has been known to boil his strings to aid in this). Last, but not quite the least, if you find your guitar going out of tune after just a few minutes and after all my suggestions then your guitar may have a problem with its INTONATION, which you'll need to take it to a guitar technician which won't cost much and you'll be very happy with the sound. One last thing to remember, if you have a cheaper guitar without locking system they're really not capable or designed for using the whammy bar that comes with most of them---this is just a feature for helping to sell the guitar because everyone wants a whammy bar---the guitar will go considerably out of tune everytime it's used. Hope this long explanation helps.

Looking at your desired notes the mandolin is standard tuned to gdae.
So three of the four notes are already available, just put the "d" mando strings where the "g" ones would go and the "g" ones where the "D" ones would go the highest is already a "e" and I am sure the "a" would tune up to a "B" with little risk.
You can also look at string sets made for the madochello or possbly octave mandolin.

Good luck,

The dude.
