Today is the first day they played the music. It's only a fee seconds and it's not obnoxiously loud, so you really only hear it around the #1 tee box and faintly at the #8 and #9 greens. All the players are laughing with each other, so they seem to be enjoying it.
Long time lurker here. I've had my eyes on a set of G30s for sometime. After reading this yesterday, I stopped by my small local shop and asked about this. They had not heard this and even ordered a set for another customer on Tuesday. I'm going back tomorrow to get fit for my own set. Can't wait!
