Question:

"Teewii asks, "hi there! im a beginner guitarist, and i bought an electric guitar from a friend for about 220$(including amp, so it was kinda cheap) even i can see that its not the best guitar in the world, but i guess its more than great for a beginner. but anyway ive been looking around the net at sites where they sell guitars, and i see many that are sold for more than 2000$ (some even more expensive). i was thinking, as i get better, i will get a new guitar, and in that case i was wondering; is there a lot of difference between expensive and "cheaper" guitars? what is different? is it just the sound? and what makes a guitar worth paying 2000$ for? please explain what a good guitar is. hope somebody can answer me. btw, this site is so great =) thanks.""
