The Mesa Boogie Subway TT-800 is the sonic love child of a legendary heavyweight and a modern track star. By fusing the harmonic soul of the iconic Bass 400+ with the nimble agility of the Subway series, Mesa has engineered a hybrid head that defies expectations. It delivers pure, tube-driven thunder in a compact frame that won't break your back.
Dual-Preamp Prowess
Why choose between vintage warmth and modern punch when you can have both? The TT-800 features a unique dual-channel design, each with its own sonic personality, powered by a trio of 12AT7 tubes.
The "Boogie" channel is your time machine, delivering the rich, blooming sag of the classic Bass 400+. Flip over to the "Subway" channel for a tighter, more articulate response that tracks every nuance of your playing. It’s like having two legendary amps in one lightweight box.
The Boogie Channel: This circuit utilizes a passive tone stack to replicate the mid-focused punch and harmonic swirl of the legendary Bass 400+, perfect for rock, blues, and players who dig in hard.
The Subway Channel: Switch over to this side for a flatter, more transparent response with an active EQ that lets you sculpt your sound with surgical precision.
Tube-Driven Texture: With three Mesa 12AT7 tubes in the preamp section, you get authentic thermal saturation and dynamic responsiveness that digital emulations still dream about.
Sculpt Your Low End
Bass frequencies can be unruly beasts, but the TT-800 gives you the whip and the chair. Mesa has equipped this head with a suite of professional shaping tools designed to tame boominess and cut through dense mixes. Whether you’re navigating a muddy stage or a dead room, the deep control set allows you to tailor your output to the environment instantly.
Variable High-Pass Filter: Available on both channels, the HPF lets you roll off sub-harmonic frequencies that waste power and muddy up the mix, tightening your sound without losing perceived weight.
Global O/D Symmetry: This innovative control allows you to adjust the clipping characteristics of the amp, moving from symmetrical, tight clipping to asymmetrical, harmonic-rich overdrive.
Deep & Bright Switches: Quickly adapt to different cabinets or instruments with these voicing switches, adding immediate girth or top-end sparkle where needed.
Professional Connectivity and Power
The Class D power section is 2-Ohm stable, meaning it can drive more cabinets than you probably want to carry, while the back panel is stocked with enough I/O to handle any routing scenario you throw its way.
2-Ohm Impedance Stability: Unlike many Class D amps, the TT-800 can safely drive a 2-Ohm load, allowing you to run four 8-Ohm cabinets for a massive wall of sound.
Dual DI Outputs: Send a pristine signal to the front of house with separate Pre-EQ and Post-Master XLR outputs, ensuring the sound engineer gets exactly what they need.
Silent Practice Capable: The headphone output and auxiliary input make this head a high-fidelity practice tool, letting you jam along to tracks without waking the neighbors.
The Ultimate Hybrid Rig
The Mesa Boogie Subway TT-800 brings together the soul of a tube preamp with the efficiency of Class D power; Mesa has delivered a hybrid bass amp head that respects history while pushing the envelope forward. It’s powerful, portable, and unapologetically professional.
