Used but fully tested and working Guitar Trainer tool from Tascam. Nice quality device that is just a few years old, you can insert a music CD and then carefully control the playback into loops and such so you can play along with a guitar, keyboard, or bass etc to learn the parts by repeated listening and playing. You can even change the tempo to be faster or slower. Doesn't come with a power plug but you can use batteries instead.
