For the back of the guitar there are three choices;
- solid, carved wood
- laminated arched wood.
- solid wood arched with braces
For acoustic guitars such as the 1923 model, the solid carved maple back gives the best in depth, quality and volume of sound.
Guitars with a pickup can also perform very well with a laminated maple back, as sometimes used in 250 and other models.
The solid wood back with braces is used in the 150 models, just like in the original Gibson guitars.
