I think no one is trying to humiliate anyone here. When you are providing a service, selling guitars in this case, make sure that the customers got the full satisfaction of trying the guitars that they choose. Afterall they are there to purchase the guitar. If I cannot try out the guitar that I am going to purchase, how am I going to know if the guitar is what I am looking for. Cannot use pick lah, can only try using a small watt amp lah. It is like Davis telling us, "Dont buy guitars from us". Then I might as well buy it from Ishibashi.
The reason for trying out a guitar before purchase is an important process. We need to know the sound. We also need to feel the neck and to know whether the guitar is comfortable to play.
I think Davis should take these criticisms constructively. And perhaps, Davis can accomodate some changes in the future.
