I’ve see a lot of information regarding Gibson Les Paul models weight-relieving, but never a condensed, concise chart about all the variations. So, based on all information I could gather, mostly from here and here, I compiled the chart below.
| Year | Standard | Traditional |
|---|---|---|
| up to mid 1982 | solid | N/A |
| mid 1982 to late 2006 | 9 holes | |
| late 2006 to 2011 | chambered | 9 holes |
| 2012 and beyond | modern |
