Just wondering what people's opinions are on the R7, R8, R9, R0 and the gibson custom shop in general. I hear a lot of guys saying that they are so much better than Gibsons line of regular production guitars, but I want to know specifically why they are so much better. What are the differences in sound, feel, playability? I know this is a subjective thing, but I would still like to hear the opinions of people who have, have owned or have played a gibson custom shop guitar. Thanks.
