I've had this one finished for a while now, but my computer at home has been destroyed by monsters so haven't been able to get online in a while. I can't upload any sound samples at work but I can assure you this sounds awesome!
I used the insides of a computer speaker connected to a 9V battery and a piezo transducer for the amp/speaker. The piezo is so sensitive it gives it a nice overdrive sound when thrown to the max! I've also used my own 10p tuning peg design for the pegs on this one, just to show how much I trust it.
