Vintage Willie Nelson & Trigger T-shirt.Trigger is the Martin N-20 nylon-string classical acoustic guitar used by country music singer-songwriter Willie Nelson. Early in his career, Nelson tested several guitars by different companies. After his Baldwin guitar was damaged in 1969, he purchased the Martin guitar, but retained the electrical components from the Baldwin guitar.
Nelson based his desired style on Django Reinhardt's playing and guitar sound. He opted to amplify the acoustic guitar, resulting in his signature sound.
