I used this kit (along with Graph Tech?s Ghost saddle set), to make a nylon string Stratocaster! It sounds very good, just as an acoustic classical nylon string guitar. I also like that there?s an option to add the ?Hexpander? kit, which gives MIDI output as well.
It was relatively easy to install. The only soldering required is the cables to the output jack.
One thing I dislike though, is that the 9V battery only lasts about 6 months. In my case I had to place the battery under the pickguard, which makes it kind of a hassle to replace.
