Any one who is trying to tell you that they can teach you "simple tricks to make you sound like a pro in one hour" is full of ****.

Learning the guitar is a bitch, it is not imposable but don't expect to be playing "Eruption" after an hour of tuition. I have been playing more than 20 years and if there were any miracle tricks, I grantee you I'd have found them by now. What I do know about are pentatonic boxes, keys and chord progressions all of which can be found on this site.

Do expect: very sore figures, months of frustration, head scratching, muscle pain, followed by your head exploding (especially on Tuesdays).

Now seriously, it takes time and there are no miracle lessons / cures /fixes etc. I'd advise finding a real teacher for half an hour a week that can sit down you you and criticize your posture etc, at least for the first couple of months. Make sure the teacher can teach you what you want to know, that will help.

It is no good wanting to play metal and getting a flamingo teacher, it will only frustrate you.

Also, it can be done as long as you dont give up, so keep at it and you will get there!

g'luck !
