I would love to learn how to play the guitar.
Oh yeah? You mean the fretted musical instrument that has six strings?
Yes. I love the sound of it.
That is nice, the projection of the sound is made using a hollow box made of wood or/and plastic. It can also be projected through an electrical amplifier.
Oh I did not know you could use that to project. I need one! Do you know a place where I can buy one for cheap?

Response: Oh yes. Friends Musical store offers many musical equipment for a very affordable price including electrical amplifiers.
