All that aside, the 6131 Jets Firebird began its life as a single cutaway with a mahogany body, dual DeArmond pickups, block inlays, and an optional Bigsby B.-3 tremolo. Near the end of 50s the changes to the Jets started in earnest, beginning with the addition of FilterTron pickups in favor of the DeArmonds. Before the turn of the decade the Bigsby B-3 came pretty much standard, the inlays had been changed to a neoclassic design, and a zero fret was added.

In 1961 the single cutaway 6131 became a double cutaway model to reflect some of Gretsch's earlier to guitars. The Bigsby tail pieces were dropped in favor of a Burns whammy, and the polished chrome hardware was replaced with gold plated. Some subtle changes to the control knobs and switches were also initiated the 1960s. From then on the 6131 Jet Firebird remained largely unchanged until 1970 when the company returned to the single cutaway design. Despite an effort to capture the past glory of the 1950s Jets, the 6131 went the way of many discontinued lines during the regrettable Baldwin era - to the graveyard of forgotten classics.
