Re: Locking Grover Mini Roto-grips vs Mini Rotomatics
Two different ways of fastening the string. Only worth doing if the basic gearing is free from lash. :banghead:

Re: Locking Grover Mini Roto-grips vs Mini Rotomatics
The rotomatics are lighter. I had a set of the rotomatics, and here's how they work: They have a sleeve around the post with an off-center hole drilled in it. The post is D-shaped. When you tighten them, the sleeve stays still until the cam catches up, then the string is pinched. There is a little detent that lines the sleeve up with the shaft. You pull the string through, then hold it tight while winding until the string is locked. Since the sleeve is drilled for the largest string, the higher strings take a bit to catch up. It gets easier once you've had them strung up once - pull the old strings, wind the post back an eighth turn, feed the new string straight through. I like 'em but I'd say the roto-grips are more idiot-proof.

Re: Locking Grover Mini Roto-grips vs Mini Rotomatics
I've had both types of tuners, and I prefer the Grovers automatic locking to the manual thumbwheel or whatever the others have. On the Grovers you just pull the string straight through the hole and start turning the tuning key. The sleeve inside the post automatically grabs the string and locks it in place as you turn the key. Easy peasy Japanesey.
I've always liked Grovers better. Cleaner look and lighter.

They don't unlock if you downtune. What's keeping them locked is the string tension - the string is literally hanging off of the pinch point. I've experimented with it when releasing tension for a string change and they stay locked until the string is flopping, sometimes longer - they'll often take a set on the plain strings and you have to grab the sleeve and pop it loose. That's what the slot on top of the sleeve is for.

It should also be noted that due to their locking mechanisms, the roto-grips have a larger housing in the back, and the locking rotomatics have longer posts.
I prefer the rear thumbscrew style myself, but it's really just preference. They are both high quality tuners that will hold the string in firmly in place.

So lets say there's a guitar that the rotomatics fit in perfectly; the roto-grips may not necessarily fit in said guitar?

No, sorry, I didn't make that clear. They will mount in the same holes. I'm talking about how far they stick out off the guitar. It's an unimportant detail.
