Mesa Boogie 6.TT8X.UK Subway TT-800 Lightweight Bass Head - Black

Sadek Music presents the Mesa/Boogie Subway TT-800 Bass Head – inspired by Randall Smith’s original Bass 400 tube design, this amp refines and blends the best of its historical predecessor with Mesa’s beloved Subway preamp and a Class D output section. The result? A genre-defying bass amp that excels at home, in the studio, and on the stage. The dual-channel design offers both a Subway channel for modern-minded clarity and a Boogie channel that delivers a rich, classic low-end character. Each channel features a dedicated EQ section for interactive tone shaping, plus four global switches that unlock High-/Low-gain voices, a Deep switch to sculpt your bottom end, and a Bright switch to sharpen your bass’s definition. Powered by a robust 800-watt Class D output, the TT-800 also includes gritty onboard overdrive. The back panel boasts an extensive I/O section with channel-specific effects loops, balanced DI outs, heavy-duty speakON speaker outputs, and more. Classic and modern, the Mesa/Boogie Subway TT-800 at Sadek Music covers all your low-end needs with arena-ready authority.
