I think of Pete Seeger and his long-neck banjo and down-tuned 12-string guitar.

Many others, like Dylan and Guthrie, are often represented in iconic images with certain instruments (the 'Fascists' guitar, of which I know there were several), but never stuck with one style, let alone one particular tool.

Are there others in the folk world that are identified with a particular make/model of instrument, or, like Seeger, identified with specific individual instruments throughout their careers?
