Something to bring up, is sometimes you have to tell people NO.People want to design their guitar and have no concept as to what will work.You try to work with them ,and tell them as nice as posiable their idea just is not a good one.If they insist let them go to someone else.No matter how good you are, someone will try to cut down your work, or talk you into doing something they want,and you do it knowing it is wrong,tell them it should not be done,and after they get it ,they grip because it does not work like they thought.And it is the builders fault,haha.I have taken jobs for people in other lines of work ,knowing I should have turned them down,and they say please.I fall for it ,and the next thing you know ,they have complained to someone about the job.If your going to build guitars for a living ,you better get some thick skin,charge what the market will bare and a fair price for your product.If you can justify what you do and the price you sell it for,sleep good at night then it is all good.
