I am going to treat myself to a decent acoustic guitar, so straight away I thought "Martin" they are supposed to be the best. But I am confused by the range of prices. What is the difference between a £600 and a £2000 model? Different woods, such as spruce and mahogany are mentioned but it's all wood to me!. Am I going to be paying for just the name (as in the case of new electric fenders)or would I be better off with another make? I can go up to maybe £1500 if I am guaranteed quality. Any advice would be appreciated.
