The Semi-acoustic guitars are electic guitars with a hollow body. They have both a sound box and a eletric pickup.
The semi-acoustic guitars are not the same as electric acoustic guitars so be careful!! Electric acoustic guitars are acoustic guitars that you can plug it into a amplifier but there is no pickup needed in this instrument.
They have a beautiful look and are classy and incredible. I say that they are incredible because their jazz and blues sound is very clean and serene.
I would personally love to have one of these guitars, for its look and its use. This guitar can be played with a amplifier our without.
Some examples of Semi-Acoustic Guitars:
Gibson 59' ES-335Ibanez AF125
