Pretty cool. Did you have to drill out the headstock, or did it fit the tuner holes? I'm a bit vary of putting power tools to my Les Paul.

And how does the weight feel? I put Planet Waves Auto Trim locking tuners (also highly recommended, btw) on my project Strat, and it became noticeable top heavy.

I didn't have to drill anything at all -- fit perfectly. Just make sure you print out the template first and check it. The install took me all of maybe 5 minutes; it took me longer to figure out how to calibrate it for the first setup than to actually get the thing on the guitar (protip: read the manual first ... I didn't).

I don't notice any difference whatsoever from the Hipshot locking tuners I put on there previously. However, this particular guitar is slightly insane, weight-wise; two heavy magnetic pickups with metal cases, piezo bridge and preamp, GK-3 MIDI pickup. It's chambered, but weighs more than an unchambered LP Custom, due to all the extra equipment. So the headstock doesn't exactly add much.

1. They fit exactly. You download the templates, and place them against your guitar to make sure the holes are going to be right.

2. The weight is probably slightly less than what you have now.

6 grover tuners from my les paul = 272 grams on my scale

The tronical tuners, including battery pack = 268 grams on my scale.
