Gibson's new version of the Les Paul Standard was released August 1, 2008 and features a long neck tenon, an asymmetrical neck profile to make for a comfortable neck, frets leveled by Plek machine, and locking Grover tuners with an improved ratio of 18:1. With the 2008 model Gibson has introduced their "weight relief" chambering, which includes routing "chambers" in specific areas of the mahogany slab body as specified by Gibson R&D. Before 2008, Les Paul Standards were "swiss cheesed." In other words, it had holes routed into the body, but it was not chambered like most of Gibson's Les Paul lineup now is.[17]
2008 Standard Traditional (2008)[edit]
In 2008 Gibson also introduced the Les Paul Traditional also known as the Les Paul Standard Traditional. The Traditional is built using the traditional Les Paul specifications; such as Kluson style tuners, 57 Classic pickups, and an unchambered body. The Traditional also comes in a plus version with the plus referring to the AAA flame maple cap.
2012 Standard[edit]
Gibson announced the new 2012 Les Paul Standard at Winter NAMM 2012. The new Standard features two Burstbucker Pro humbuckers with coil splitting, and Pure Bypass. Pure Bypass gives the option of bypassing the volume and tone potentiometers, sending the signal directly from the bridge pickup to the output jack. The 2012 Standard also features Gibson's "modern weight relief" as opposed to the chambered body of previous Standards. Other changes include a phase switch and compound fretboard radius.
