This instructable will teach you some basic lead guitar skills and techniques to use when starting out lead guitar or merely getting a kickstart from a low level playing.
First of all i would like to point out that i am no expert at guitar.
Second i play lead guitar and i don't know a lot about chords and other techniques used in rhythm
Step 1: Buying your first guitar.
My first mistake was buying from ebay, im not discouraging buying from ebay, all i could reccomend is you try out the guitar you want from a guitar/music shop first when your happy with it then by all means buy it from ebay, however if you cant find the make of guitar in your local music shop then this is a sure sign that it isnt good.
My second mistake was not researching guitars,
Here are some things to look out for when buying a new guitar (assuming you can play and inspect the guitar you want). The best thing to do if you are not sure about a guitar is to bring a friend along who has been playing for a year or two and has had some experience with buying and maintaining a guitar.
First of all, you want to inspect the body. If it is a used guitar, are there any major dents or scratches? Are the electronics in working order? Is anything loose or rattling? If it's a new or used guitar, ask someone from the shop to "set it up"- check the intonation and fretboard, etc. They'll probably know what you mean :). If you're completely clueless ;-0, ask if they know any good beginner guitars. Their job is to make you want to come back to their store again, so you'll most likely get some good tips.
Secondly, the fretboard. Are the frets to large or small? Does the guitar feel comfortable in your hands? If you know how to fret a note, check both the low and high notes on both sides of the fretboard for any buzzing (assuming you're fretting the note right), especially the last four frets on each string and frets 7-12. Run your hand along the fretboard to make sure it isn't sticky, scratched, or dented. Make sure that the frets are all straight and none of them run off the edge of the fretboard.
Finally, play something on the guitar. Don't worry about whether what you're playing is "cool" enough to play, or worry about making mistakes. Play through the same type of amp you plan on getting, and try different settings and tones to see what you like. If it's comfortable in your hands and has a good sound, that guitar might be the best for you. There may be other players at the store you're at who are playing fast and looking cool, but don't be intimidated! Your job here is to waltz in, find a good guitar, and waltz out. Also, this only applies to certain people, but don't feel intimidated about asking a sales rep if you can try out three, four, or even ten guitars. You're doing them a service by buying one of their products, and as long as your intent is to buy a guitar, they'll be happy. Be careful with the expensive guitars though :)
Remember a couple of things- If the guitar comes with a crapload of stuff (amp, case, statue of Jimmy Page), you may want to look a bit closer at the guitar itself. It would really help if you knew a couple of songs and could play them moderately well.
