What kind of music has developed an alvarez acoustic or electric guitar to play?
Whatever kind of music you want to play it. An acoustic or electric guitar is not likely to enter the desired sound for heavy metal and hard rock lead solos, for example. But You can use it for any musical situation in which a strummed acoustic guitar sound – Whether flatpicked or fingerpicked – would be appropriate. Basically the idea that is behind an acoustic or electric guitar, that by setting a pick-up in an acoustic guitar, it gives you an acoustic guitar sound, without having to increase the player to sit or stand motionless on the stage, while playing into a microphone. So you can move around on stage, while you play. It also cuts down on the amount of feedback that is often when you try to play on an acoustic guitar into a microphone at high volume.
