Using D'Addario Planet Waves Auto-Trim Tuners for the first time.

Read my little review below:-)These tuners are pretty cool. They lock and automatically trim your strings. In practice, I see these as being mostly gimicky at best. I'd prefer just to cut my own strings if I'm honest. This took way longer to string up than any other set of tuners I've ever used. Granted it was the first time, I still think the entire affair is a bit needless. Just get a pair of wire snips and regular old set of locking tuners for my money:-)
