This instructible is based at complete beginners if you have played the guitar before then some of this may seem very obvious but if you haven't its not!
Step 1: Getting A Guitar
Guitars can cost anything from about Â£5 (~$10) for a second hand acoustic in a charity shop to thousands of pounds. When you are a beginner just about anything you can get will do as long as it is not too damaged and has 6 strings, you can always upgrade it later.
If you have an electric guitar you will need an amp and lead (see pictures) but whatever you have you have I would recommend buying a plectrum (A.K.A pick) choose a medium or light type as they are most suited to beginners.
You could also get a tuner but they are not totally necessary (see next step)
