Stephen Stills

The photograph from Stephen Stills' concert on June 1, 1980, at the Concord Pavilion in Concord, California, provides clear evidence that he utilized a Roland JC-120 Jazz Chorus amplifier during his live performance. This image, showcasing both the guitars and amplifiers employed by Stills in that set, serves as a direct source confirming his use of this specific piece of music gear.

In a photograph shared on Pinterest by Russ Ell, Stephen Stills is seen performing live with a Fender Bassman 6G6-A/B Brownface 50-Watt Guitar Head from 1962 to 1964 clearly visible in the background of his setup.

Stephen Stills can be seen using a burst Gibson Les Paul Standard, with a Bigsby and without a pickguard, during his time with Manassas in 1972, as documented in this video of Manassas playing “Rock & Roll Crazies” for a TV special filmed in Germany.

Stephen Stills used the Guild DE400 early on in Buffalo Springfield, and can be seen with it in this photo shoot.

Stephen Stills has confirmed his use of the Gretsch Country Gentleman guitar. In an interview with MusicRadar, he stated, "I have two old, brown single cutaway Country Gentlemens, and they’re really, really good." This highlights his preference for the instrument and provides evidence of his ownership of this specific gear.
