The Norlin era guitars have a lot going for them. The maple necks are far more durable than the mahogany necks. The electronics were still top rate and some of Gibson's most iconic pickups come from this era. The original dirty fingers and the Tim Shaw's are some of Gibson's best in my opinion. Gibson did a lot of experimenting in this era. There are many models that originated during this time and became staples of the Gibson lineup. And let's not forget that many of today's collectors grew up during the Norlin era so these are the guitars we lusted after in the music stores as kids.
