The first Les Paul I ever played was a white custom owned by the lead player in my mates band. I can say without doubt it was the best and coolest guitar I ever picked up in my life and that even includes my beloved 90's Standard.
So it turns out I have another Les Paul from Norlin period. My other one being #610 in the Norlin period thread.
It is a Les Paul Custom from 1979 and according to the shop where I bought it the finish is not that common. It is called Pearl White. I have check around on the forum and I haven't seen any so far. But I just joined. Maybe someone has some info about why it is rare. It really glows when the light hits it. Hard to capture on the iPhone though...
It has the flattest radius of all my Les Pauls and other Gibsons. Only one other guitar comes close and that is my Ibanez JEM. Is the flat radius common for the Les Paul Customs? It has been refretted at some point before I bought it. I think the nut has been changed too and I am suspicious about the chrome knob on the pickup selector. Otherwise it seems to be all original. I still have the shops notes on the back and it says Weight 5040g and Pots 4x1377824, PU 2xGibson Epoxy filled.
I believe it's all about light, oxidation and the pigments they used in the dye. Mine is almost 30 years old but the prior owner had it in a case most of the time so mine looks new. I am sure you can send it out for an "aging".
