Grant Green

"You’d be guessing all this chocolatey tone issues from a deep-bodied acoustic-electric Gibson archtop … and you’d be wrong. From his arrival in New York City in 1960 until the mid ’60s, Grant Green played a Gibson ES-330. It’s hollow-bodied, but a thinline double-cutaway model with the body lines of the ES-335 and a rim depth of just around 1 3/4 inches. Gibson had introduced its first thinline archtops in 1955, in the form of the ES-350T and the Byrdland, and brought the radical new ES-335 to the line in 1958. With a solid block through the center of the body to combat feedback and aid sustain and a neck joint around the 20th fret, the ES-335 was an instrument with jazz roots, but employed new features that would appeal even more to rock, country, and blues players."

During his recording sessions (as a sideman and leader), Grant used two different amps that Rudy Van Gelder has in his studio. These amps were a tweed Fender Deluxe, as well as various Ampeg Models. Here, during the recording of Idle Moments, it looks like he is using an Ampeg Jet.
