The first thing that hits you when looking at the jamstik+ is, "hey, what happened to the head"? Well, folks, the jamstik+ is the new "SmarGuitar" no need for a head (except your own). It's a digital guitar that works over Bluetooth to connect to your other devices so you can... Jam. Marketed as a new way to learn how to play guitar, it comes with a few free apps with guitar lessons.
But they don't stop at the newbie level. Since the jamstik+ can function as a midi controller, you can use it numerous ways, including obviously being able to change the sound or voice of the guitar to whatever you want.
It's a cute concept and certainly speaks to anyone who wants true portability without sounding like a ukulele.
