I really love my 1998 SG Special (the serial number is dated exactly to the day I was born) but the one thing I don't like about it is the tuners. I think they're Kluson deluxes, not too sure. I find them too loose and tuning is not always stable particularly when bending notes. I've been thinking of replacing them with Grover Rotomatics which is a common mod but I've read some peoples comments saying that a switch over isn't necessary and can effect tone and weight (though its not something that bothers me too much). Shall I switch or do something else to solve the issue? Suggestions?
