Playing guitar might be a lot of fun, but you can’t always carry your six-string around with you everywhere you go. Think of a melody you want to strum out while you’re on the go? No worries, the virtual guitar app known as Solo has got you covered. This awesome Android App lets you play the guitar while you’re on the go, but it does a lot more than that. It’s a great learning tool as well that has more than enough features to keep any guitar player happy.
