An escopetarra is a guitar made from a modified gun, used as a peace symbol. The name is a portmanteau of the Spanish words escopeta (shotgun) and guitarra (guitar). The term “Escopetarra” is a misnomer, since all escopetarras to date have been fashioned out of rifles, not shotguns.
Escopetarras were invented by Colombian peace activist César López in 2003 at a gathering after the El Nogal Club bombing in Bogotá, when he noticed a soldier holding a gun like a guitar. The first escopetarra in 2003 was made from a Winchester rifle and a Stratocaster electric guitar.
