Re: 70's Era Gibsons
I think on average Norlins were pretty bad quality-wise as they were cutting LOTS of corners. However I think most of the "ire" comes from the Blues Lawyers on the internet -In many cases they are right about quality, however there are some things that are def personal opinion, like for example, neck shape and material. I like Maple necks on a Les Paul- different sound, yes, but it's not bad, just different.
I'll take a Volute ANY day over a non volute. Its a better structural design, and addresses a common problem with les Pauls and other Gibsons- Especially those that don't have a baseball bat for a neck.
I had a pancake maple neck Norlin Deluxe and it was awful, but mostly cos it had the tinniest, thinnest minis I've ever heard. Guitar was actually pretty solid build-wise.
However my actual 76 RI Explorer with T-tops STILL is the benchmark Gibson sound I hear in my head.- Those pickups rocked, as do DFs and Shaws (also Norlin era products). Sorry, but I prefer the T-tops and Shaws over ANY Duncan and most Dimarzio PAF styles I've played/tried.
Some don't want to admit it, but there has been alot of classic guitar sounds made with Norlin era guitars. They may not be the same as the the classic sounds of the 50s Gibsons, but they are classic none-the-less.
