This decade found Jack playing jazz 7 nights per week in duos, trios, quartets and with the 12 piece Chuck Howard Superband. A high point for Jack was playing duets on classical guitar in concert with noted tenor Luciano Pavarotti. Jack studied 1990-93 with George Van Eps
working on solo guitar technique resulting in his first solo guitar CD, "Solo Burner". The CD immediately sold out and is in its third printing. From 1994 to 1998 he studied with Tal Farlow. Tal taped some of their duo sessions which Jack captured on the CD "Two Guys With Guitars." To facilitate studying with Tal in New Jersey while living in Wisconsin, Jack secured a teaching job at the National Guitar Workshop in nearby Connecticut. Many recordings followed as Jack continued composing music for new CDs.
By the end of the decade, he had invented an instrument he named the "SuperAx"
which enabled him to play bass and guitar simultaneously. His friend, guitarist Kirk Tatnall, built one also. With various drummers, they performed as a trio for 12 years at The Uptowner, producing two CDs of Jack's compositions: "Live @ The Uptowner" and "Ghost Ridge". Working part-time for music publishing giant, Hal Leonard, Jack wrote the book trilogy, "Jazz Guitar Favorites", "Jazz Guitar Standards" and "Jazz Guitar Classics
