A basic guitar tuner. This one is larger than the QT 11. But has a similar feature set. It is fixed to tune the EADGBE notes. You can go through the 1/4 in. plug or you can pluck into it's mic.
It's a plastic case with LCD display I've had it for 3 years still the same battery.
I chose the QT-8 because of price, quality and ease of use. It is one of the most useful accesories I own.

One thing before you go on, this is a QT-8, I got it confused with another one :)
This little tuner will tune a guitar or bass, acoustic or electric as it has a 1/4" jack and a mic. Also has an out jack for passive tuning.
Great, turns off automatically so it won't run down the battery.
