The Gretsch 6128 Duo-Jet stands as one of Gretsch's most iconic guitars and certainly its most iconic solidbody. This chambered solidbody is most closely associated with George Harrison who played one in the early Beatles era and throughout his whole career. George’s ’57 Duo Jet was his sentimental favorite and he described it as his first “good guitar” when he bought it used in 1960. It’s unique tone shaped the sound and energy of the Beatles’ early recordings. Vintage Duo-Jets are amongst the most prized Gretsch solidbody guitars. It is one of the best kept secrets out there.
Another notable player is Jeff Beck. His Duo Jet is a '56. Other than the fixed-arm Bigsby and aluminum Bigsby bridge, it appears to be stock. It is close but not quite identical to Cliff Gallup's 1955 Duo Jet. Jeff drew a lot of inspiration from Cliff Gallup. It is certainly what Jeff was after sounding like on his "Crazy Legs" album. I think he got there; it's a fabulous album.
What I have in my collection is a 1956 Gretsch 6128 Duo Jet. This guitar has all the George Harrison"s specs minus the bigsby. It has block Inlays, G brand tail piece, Melita bridge. It is light weight, looks gorgeous and a Very cool guitar. The two DeArmond pickups sound very nice. They are fat single coils, think P-90s and a Tele mixed together. They can pretty much do it all, Jeff Beck also has a similar 1956 Gretsch 6128 Duo Jet (very similar other than the fixed-arm Bigsby and aluminum Bigsby bridge which were probably added).
Other notable players include David Gilmour, Pete Townshend and many others.
