Hi, Recently, i took an expensive custom jazz bass to a technician to have it set-up. All i asked for was a set-up, nothing else. This particular bass has screw holes in the body where the neck and bridge pick-up covers were once attached. You know the deal, it's fairly common on jazz basses. When i bought the bass, i removed the covers. Last time i checked, the screw-holes were tight, eg, you put the screws in and they would screw in tightly. When i got my bass back, there were two screws placed in the holes at the neck pick-up. I am pretty sure that i didn't do that. When i remove the screws (because i want to put the neck pick-up cover back on), i notice that the holes are loose and that the screws don't sit as tightly as they used to. There was even saw-dust coming out of one. I suspect that the technician put the screws in with an electric screwdriver, which means that they were inserted with more force, which has made them bigger and less tight. The point is, i did not ask for anything else to be done to my bass other than a 'set up'. How dare they touch my bass like this? I am annoyed. But, there is nothing i can do, as i did not get a receipt and to tell you the truth, i am tired of holding people accountable for things that they do wrong. It's almost easier to walk away and not go back to them. Technically, the rest of the bass is NOT in the same condition as it was when i took it there... What this means is that i now have to find some putty and have it applied professionally, as the holes will only get bigger with time and eventually will become so worn that the screws won't sit there properly and the pick-up cover could become loose. I really don't get some people's mentality with being rough with other people's property. What would you do?
