I got this guitar for Christmas from my parents. It was the fourth guitar I've owned and is defintely the best. My parents bought it for I think $650. I bought it at a small music store in Windsor, Ontario Canada called Riverside Music.
This is a great acoustic/electric guitar. I use it most of the time unplugged to play acoustic stuff like staind, and i make a lot of acoustic versions from other songs i love. It has a wonderful acoustic sound by itself.
The SF-1 does not have a very good sound when plugged in. I run it through two Boss monitors because they sound clearer than my peavey amp. It sounds like a hollow electric guitar. I have used it at masses before for the music and it does sound better in a large church than in my bedroom.
It's a sold body guitar. With great pickups and 4 band fishman eq. Low, Mid, High and brilliance.
It's definitely sturdy enough for the abuse my guitars take.
