I'm curious about something. I too have been contemplating replacing the tuners on a ZM that I have pre-ordered. The Phase III tuners look awesome although I know they are not a direct replacement. The other Kluson locking tuners that have been discussed in other threads seem like cool options too.
After thinking through the cost of new tuners...any of them...I also got to thinking...why am I thinking about doing this. My question is are the stock tuners that bad? Just curious considering the cost of Phase III tuners versus the cost of the guitar...kind of a big decision.
