The Gretsch 6128 (Duo Jet) is a chambered solid body electric guitar manufactured by Gretsch since the mid-1950s.

Made of a chambered mahogany body, the Duo Jet model 6128 is one of Gretsch's most sought after guitars. One of the most notable differences between the Duo Jet and comparable guitars is in its configuration variations. While it shares their dual pickup, single cutaway style with the more popular Gibson Les Paul, the 6128 Duo Jet models take various unique approaches for shaping the tonality of the instrument.

While a master volume is standard on this model, some variations will have either independent neck/bridge pickup volume knobs with a master tone knob, or the same independent neck/bridge volume knobs, with a tone switch next to the pickup selector switch rather than the master tone knob.

The versions with a master tone knob are equipped with Dynasonic (aka DeArmond) pickups, which are extremely popular for a classic full-bodied, low frequency tone. Most associated with the sound of guitarist Duane Eddy, Dynasonics are single coil pickups, and have been used on certain Gretsch models since the 1950s. Most models of the guitar come equipped with a Bigsby vibrato tailpiece in conjunction with a rocker bridge.

The most famous example of this Duo Jet was played by George Harrison during The Beatles' early days in Hamburg, and on their first few albums. Harrison also posed with the guitar for the cover of his 1987 solo album, Cloud Nine.

The tone switch versions of the Duo Jet come equipped with Gretsch's own Filtertron humbucker pickup made popular by country music guitarist Chet Atkins, and are still in demand to this day. Notable players of this version include David Gilmour of Pink Floyd as well as George Harrison.
