This is a really cool little device which is ideal for practice or playing alone in your bedroom! It has hardly been used and comes with manual and box. It has a built in tuner, metronome many drum patterns and you can even pick your own amp sound such as fender twin reverb, Marshall, AC30 etc. there is a headphone output or you can go into your own amp. There is aux input for mp3 so you can play along to your fave tune or even your own recorded music then output to overdub yourself. This was around £80-£90 new so £45 seems like a fair buy it now.
