Thanks for those that posted parts that work. I've been thinking about putting locking tuners on my Variax standard and like the auto-trim feature of the Planet Waves version, but am not sure if I would need to modify the hole diameter. Also for those of you using the locking tuners, have you had issues with the high E and B strings slipping out? I use .09 gauge and have a set of Billy Gibbons .07 I want to try but I've read that the lighter gauges can slip through some brands unless they are double-looped through the tuner.
