Old Know It All
Some people do hear and sense a difference in the sound of a guitar with lighter or heavier tuners.It came with heavy metal buttons. My luthier is well trained, talented, and very observant. He told me to try that as a first step. He felt the guitar was out of balance sonically. He’s also a guitar player and former factory employee.
Those people might have a preference for one or the other.
All a matter of taste.
It became fashionable in the 60's and 70's to swap out Klusons for heavier Grovers.
Now it's fashionable to use lighter Klusons.
