The MESA/Boogie® Bass-800D redefines professional bass amplification by combining the legendary valve tone of the iconic Bass 400+ with the power and portability of the Subway® Class D series. Designed for players who demand vintage warmth and modern versatility, the Bass-800D is a compact powerhouse built for today’s touring and recording bassists.
Its tube-driven preamp is directly inspired by the revered Bass 400+ architecture, enhanced with Boogie® Channel topography from the Subway® TT-800 for added warmth and dynamic range. The result is a harmonically rich foundation with authentic valve character and expanded overdrive capability—perfect for genres ranging from funk and R&B to rock, metal, and beyond.
Instead of the 400+’s graphic EQ, the Bass-800D streamlines tone-shaping with intuitive front-panel controls: Low/High Gain, Deep, Bright, and a rotary High-Pass filter. These smartly designed switches let you sculpt your tone quickly and musically, without the fuss of surgical EQ adjustments. At 800 watts of Class D power, this head delivers explosive punch and clarity while remaining lightweight and travel-friendly.
With modern connectivity including dual SpeakON® outputs, headphone out, AUX in, tuner out, a mute remote jack, and USB device charging, the Bass-800D is equally at home on stage, in the studio, or on the road. Built in Petaluma, California, it honors Mesa’s storied heritage while embracing the future of bass amplification.
