Semi-acoustic guitars have several uses for the modern player. On the one hand they are of course perfect for traditional Blues and Jazz – great rhythmic instruments that combine the twang and airiness of the semi-hollow body with the meatiness of (usually) humbucking pickups.
On the other hand, they've found just as much favour on the rock circuits, and anyone from Oasis to the Smashing Pumpkins have used semi-acoustic guitars to great effect on records and on stage.
For those who find the size of some of these instruments a little daunting there are thinline versions available, and for expressive vibrato you'll often find Bigsby tremolo systems waiting at the bridge too. To flesh out your tonal arsenal significantly and bring a unique style to your live sets, a semi-acoustic guitar might well be the answer.
