I think what many don't realise that the 70's and 80's were all about "progress". Older designs were shelved and newer more radical ones were implemented. For both gibson and fender there were some radical changes, and some new thinking. Buying a guitar from this era is often a disappointment for people because they simply assume it will be a slightly younger version of a 60's guitar. In that way buying a new AVRI or RI gibson will be better, simply as they have only one very narrow definition of a great guitar. If you can learn to open your mind and judge guitars on a much broader basis then there are many gems out there waiting to be found.
