I saw this thing today on digg.com. It’s quite a natty idea – one of those “why didn’t somebody think of it before” things. I find myself constantly re-tuning my guitar, mostly due to me either playing quite hard, or changes in the temperature/humidity of the room affecting the guitar. Something like this would be quite nice to just hit a button and it’s back. I can see a few custom guitar models sprouting these units. Some guitar-purists will probably sneer at it, but then again I bet some people did when the trem first came along, or locking tuners. According to the guy in this video, the unit will sell for about $800USD. I don’t think I’ll be getting one just yet!
