Launch massive low-end from a featherweight command module with the Mesa Boogie Subway® D-800 Bass Head—now orbiting at Interstellar Guitars.

Weighing in at just 5.5 lbs., this ultra-compact Class D powerhouse delivers a commanding 800 watts of pure MESA tone—enough to fill anything from intimate clubs to sprawling cosmic arenas. Small in size but immense in output, the D-800 is built for players who need serious power without hauling a heavy rig across the galaxy.

Infused with MESA’s legendary bass DNA, this head draws inspiration from iconic designs like the Bass 400+, Strategy 8:88, and Carbine series—blending warmth, punch, clarity, and fast response into a voice that’s both familiar and forward-looking. The result is a tight, articulate foundation that cuts through any mix while still delivering rich, musical depth.

Tone shaping is intuitive yet powerful. A 4-band EQ gives you precise control over your sound, while the continuously variable Voicing control lets you sweep from a flat, honest response to a deep, modern scoop with enhanced lows and highs. Need even more depth? Engage the DEEP switch and unleash a subsonic wave of low-end that feels like it’s bending gravity itself.

Designed for real-world performance, the D-800 includes essential tools like an Active/Passive input switch for perfect headroom matching and a Mute function for silent tuning between sets. Around back, pro-level connectivity ensures you’re ready for any mission—whether you’re running direct to a console, practicing silently with headphones, or powering your favorite cab with rock-solid reliability.

Portable, powerful, and endlessly versatile, the Subway D-800 is your all-access pass to massive bass tone—no matter where in the universe you play.
