The Kitty Hawk Testarossa is a high-gain channel-switching head named after the Ferrari sports car, reflecting the aspirational, performance-oriented marketing of boutique amps in the late 1980s. Its gain structure is more aggressive than earlier Kitty Hawk models, pushing further into metal and shred territory while retaining the brand's characteristic note separation. The Testarossa was Kitty Hawk's answer to the Soldano and Mesa Boogie high-gain movement.
