I've had a Gould Les Paul copy for a few years now.. and it looks the balls and sounds quite good too but I've always had some issues with it..

I'm looking to replace the machine heads from the snot-green ones it came with to some nice gold ones that will hold my strings in tune for longer, I've looked around and found a few I like but are machine heads the same size universally? Or.. not?

If this goes well I may turn it into a bit of a project cause I really miss playing this guitar
Well I got this guitar and I learned how to make it talk...
i'm sure what ever you get will fit, but if they're to big, its not very hard to widen the hole, if they're to small than i guess you're SOL.

but there's not much i can tell you with out a brand of tuner, or pictures
