One of the best was to keeping your guitar in tune, is to also string it correctly and use new strings . Make sure the first winding of a new string around the tuner post goes over the exposed tip of the new string. The rest of the windings go under the exposed tip of the string. This will keep the string clamped firmly in place. Use 4-5 turns around the post for unwound strings, 2-3 for wound strings, in a downward spiral towards the bottom of the post as shown in the photo.-Tom, 30yr player.

To lower the action on an acoustic guitar:

Usually just the saddle needs reducing.

1. Remove strings (or you may be able to just loosen them). Remove saddle, sand down the bottom a little at a time. Restring and check action.

The action can be set as low as poss without any fret buzzing or note choking on all strings and on all frets.

2. Repeat 1

If the action remains too high then there are other techniques.

How to Change Strings on a Dean Vendetta Guitar

Dean Vendetta is a company that makes a wide range of electric guitars. These guitars are used by famous musicians and bands such as Alice in Chains and Megadeath. If you own a Dean Vendetta guitar, you will need to change the strings periodically in order to keep your guitar sounding bright and crisp. Without changing the strings, your instrument will sound dull due to dirt and oil build-up on the strings.

Instructions

Things You'll Need:

* Dean Vendetta guitar
* String winder
* Guitar strings
* Electronic tuner
* Wire cutters


Locate the high E string. This is the string that is highest and thinnest and closest to the ground when you play the guitar.

Loosen the high E string by turning its tuning key counterclockwise. Use a string winder for this if you have one. Pull the string off of the tuning peg and out through the bridge.

Insert a new high E string through the hole in the bridge, up the neck, to the head of the guitar.

Thread the string through the hole in the tuning key so that about two inches extends beyond the hole.

Hold the string at the top end of the neck in one hand as you turn the tuning key clockwise with the other hand. A string winder makes this task much easier.

Continue to wind the string until it tightens to pitch. Use an electronic tuner to check the pitch.

Clip off the excess string with wire cutters.

Repeat these steps to install the B, G, D, A, and low E strings.


Tips & Warnings

*
Expect to re-tune often for the first few hours after installing the new strings, as they tend to stretch quite a bit at first.

Hope it helped.

Thanks for using fixya..

Considerations:

1. Intonation problems can be due to worn strings even if the guitar is set up properly. New Strings can fix this. This is the most common problem.

2. Also, changing string size may effect your set up too. Typically, new guitars come with lighter strings such as (9's) which the guitar is set up for. The positive is that 9's fret easily. The negative is that they bend too easily for some players who either slightly bend them when chording (accidentally), or press too hard on guitars with jumbo sized frets, which in turn bends the string toward the fret board causing detuning. To fix these items folks may suggest you get a heavier string like a (10), but the problem can often be solved by playing with a lighter hand, pressing only enough to make contact with the fret and not pressing the string all the way to the fretboard. Check your intonation using this light touch method and see if it's okay verses pressing the string all the way to the fretboard. If the intonation is okay with the light touch, the guitar intonation is set up properly. You may want to consider playing with a lighter hand or getting a guitar without jumbo frets such as Fender strats etc...

Putting a heavier string on a guitar set up for (9's) would likely cause the buzzing that wasn't there before. In this case you'd need the guitar and neck set up again to accomodate the 10's. So decide what size string you want and set the guitar up for that size.

These considerations are true for any electric guitars.

After consideration of all of the above, you still feel it's the guitar, I suggest you push for a replacement or perhaps credit toward another guitar.

A new type of peg that makes it easier to change strings!

Either that or most guitar shops stock string pegs, Just ask at the counter .. .If they don't have them and can't get any in then they are not a real guitar shop in my opinion

the washburn X10 is an electric guitar.

first thing you you want to make sure of is that you ask for electric guitar strings

next consider what kind of music your are playing...

heavier music or really moody warm tones your going to want thicker strings

med to heavy guage

if you want clear crisp tones than go with lighter guage

light to med

lighter guages are also easier on the finger tips.

the sizes usually refer the the smallest string on the bottom or the first string.

9 is the light 10-11 is med 12 is heavy

you might also want to consider nylon coated strings

they last longer

have great tone

easy on the fnger tips

but they cost more

Sometimes the truss rod (nut you are referring to) will do the trick. The truss rod runs under the fingerboard and allows you to give the neck relief or tension. Some truss rods are dual action but I'm guessing yours is designed simply to give basic relief of the neck. I would make sure the truss rod is adjusted properly before sanding down the saddle. If you sight down the neck you should be able to see the relief in the neck - just use the string as your straight-edge. Most guitars need a slight amount of relief but higher-end guitars can be almost straight (better fretwork.) Once the neck has been adjusted correctly you can move forward with the setup.

Make sure the nut is also the proper height. If the nut is too low (1mm height between bottom of string and first fret) you should get it replaced by someone capable of doing such a thing. If the nut height is okay I would suggest moving forward cautiously by sanding the bottom of the saddle. Make sure this is done patiently and carefully as it can drastically change the sound and playability of the guitar. Hardly any material needs to be taken off to lower the action just a little. Error on the side of not-enough than too much. Make sure the bottom of the saddle remains flat! If the bottom isn't flat the guitar can sound horrible and if there is an undersaddle pickup it might not pick up evenly. The easiest way to do so is to tape some sandpaper rough side up on a flat surface (just don't pick something like mom's heirloom or something important in case it gets scratched.

Good Luck!

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.
