For a free guitar, with the purchase of a car, it was a fun guitar. I kind of wish I hadn't sold it when I moved since it was such a neat novelty item. The preamp, built into the guitar, was an interesting feature that I was always scared to really use. Sound wise it was quite decent for a bonus giveaway item.
The guitar itself and its tone are pretty good. However, because of the preamp system, you can't customize any of the electronics. The pickups are unique and the preamp won't work without them because they are both active and passive, so you can't replace the pickups. The preamp prevents you from making any big changes to the electronics because all the knobs and switches are built into a circuit board, so to change one thing you'd have to change everything else. But the guitar works just fine and the preamp is pretty cool
