1 mr jimi 3 months ago Just got a sweet price on a minty LP 2012 Studio Limited. Beautiful fireburst nitro finish, slightly chunky neck, P90 at the neck, Burstbucker bridge. Just lovely. A nice, little Lester with great potential... with one little problem. It's a full monty 4th generation Robot - self tuners AND some other jazz built into the body that I have no idea what they do.I'm seriously thinking about swapping the tuners with Grovers. Now if this were just about the tuners it would be no biggie BUT with this one the tuners are integrated somehow with a PCU and a control knob (an "MCK") on the body.I haven't had a chance to look inside anything yet or even totally read the 40 page owners guide. I'm starting on a basic luthier class thus Saturday and this may be my first project, with my instructors help.Anybody out there have any experience/opinions/resources on this sort of thing?
