Solid Mahogany Body and Set-Neck Construction
Two of the most central features of the Billie Joe Armstrong Signature Les Paul Junior are its solid mahogany body, and its set-neck construction, or glued neck joint. Like the majority of Gibson's classic guitars, the neck of the Billie Joe Armstrong Signature Les Paul Junior is set into the body's neck cavity using glue, which ensures a "wood-to-wood" contact, no air space in the neck cavity, and maximum contact between the neck and the body, thus allowing the neck and body to function as a single unit. The result? Better tone, better sustain, and no loose or misaligned necks. As with all Gibson woods, the regimen involved in selecting the right body wood and the formula to dry it out is extensive. First, the wood is personally inspected and qualified by Gibson's team of skilled wood experts before it enters the Gibson factories. Inside the Gibson factories, humidity is maintained at 45 percent, and the temperature at 70 degrees. This ensures all woods are dried to a level of "equilibrium," where the moisture content does not change during the manufacturing process. This guarantees tight-fitting joints and no expansion, and controls the shrinkage and warping of the woods, in addition to reducing the weight. It also improves the woods' machinability and finishing properties, and adherence to glue. Consistent moisture content means that a Billie Joe Armstrong Signature Les Paul Junior will respond evenly to temperature and humidity changes long after it leaves the factory.
Wraparound Tailpiece
A classic piece of hardware, the non-compensated wraparound bridge/tailpiece on the Billie Joe Armstrong Signature Les Paul Junior offers a simplicity and functionality that is hard to match. It provides a firm seating for the strings, and allows the player to adjust intonation and string height as needed. It also yields a great union between the strings and body, which results in excellent tone and sustain.
