This Fernandes ad comes from Guitar Player, August 2001. In those days Robert Fripp and Adrian Belew were back in the saddle with King Crimson, having released The ConstruKction of Light the previous year. Fellow endorser Reeves Gabrels was into his post-Bowie solo career, Ulysses (Della Notte) being his most recent issue.
The text also cites Steve Vai, The Edge, and Steve Lukather as Fernandes Sustainer users.
