Re: If you had the money, would you spend it on a Les Paul Custom ?
I think in addition to my earlier posts I want to answer the original question more directly.
The currently made LP Custom is very expensive. But it is made pretty much the same way as the LP traditional, including the swiss-cheesing weight relief, questionable pickups and the Nashville TOM. The only difference is that it is being made in the custom shop, and the ebony board. It is really unclear whether being made in the custom shop has any practical value over whatever they call their other shop, but it is why it is so expensive new, and it is partially (only partially) being rewarded when trading used. So, there is nothing of substance here. The only thing that lifts it a bit is if your non-CS Les Pauls have construction issues you don't like such as laminated fretboards, PCB electronics or the like.
Now, for about the same money the Gibson CS also makes historic Les Paul Customs, the 57 and the 68, both with ABR-1s. The 57 has a carved mahogany top and should under no circumstances be bought without playing it first. The 68 is chambered. How that is supposed to be historic is a bit unknown to me. Owning a 1970 LPC I can assure you it isn't chambered. I rate this as a typical Gibson WTF moment. It is marketing. They had to make the 68 historic different from the non-historic custom and pulled a random stunt. How this deserves the "historic" brand is beyond me.
So, in a word, yes they are pretty, especially the wine red ones with gold and ebony, but things have been carefully stacked against the buyer to rip him off. Good guitars, but about the most overpriced currently being made.
