(formerly Gibson Guitar Corp.) is an American manufacturer of guitars, other musical instruments, and consumer and professional electronics now based in Nashville, Tennessee. Gibson invented archtop guitars by constructing the same type of carved, arched tops used on violins.
The company was formerly known as Gibson Guitar Corp. By the 1930s, the company was also making flattop acoustic guitars, as well as one of the first commercially available hollow-body electric guitars, used and popularized by Charlie Christian.
he easiest way to find the year of manufacture of a particular Gibson guitar is to reference the instrument's serial number of factory order number.
In the 1970s, Gibson standardized the serial number system that is still in use today.
Several Epiphone Les Paul models are very close to the classic Gibson models upon which they are based, while other models are designed with different features to keep the entry price low for students and budget-minded players.
