Boogie Bass Tone for Today’s Bassists
A legend reborn. The MESA/Boogie® Bass 400+™ was the flagship of MESA’s tube bass amplifiers, dominating the 80s and 90s with its rich tone, boutique build, and unmatched power. With its musical tube preamp, 7-Band Graphic EQ, and a 12x6L6 output section capable of delivering instant punch and authority, it set the standard for professional bass tone.
From jazz to funk, blues to arena rock, top players trusted the Bass 400+ for its clarity, attack, and stage-leading presence. Now, that iconic sound has been reimagined for the modern bassist—retaining its warmth and nuance, but without the weight and bulk.
Introducing the MESA/Boogie Subway Bass-800D. This Class D powerhouse draws inspiration from the Bass 400+ while incorporating the best features of our Subway™ line. Its tube preamp architecture is rooted in the 400+, enhanced with Boogie® Channel elements from the Subway TT-800 and refined gain staging for even more warmth, dynamics, and organic overdrive potential.
Instead of the old graphic EQ, the 800D offers simple, effective tone-shaping tools: Low/High Gain switch, Deep and Bright voicing switches (with bypass), and our highly praised variable High-Pass Filter for tightening low end and cleaning up mixes. These intuitive controls deliver fast access to rich, musical tones without the hassle of detailed EQ tweaking.
Modern upgrades include SpeakON® locking speaker outputs, flexible impedance switching (2/4/8 ohm), headphone out, mute footswitch jack, Aux In, Tuner Out, and even a USB power port for convenience on the go.
Now, you can get the legendary Bass 400+ tube tone—warm, articulate, and commanding—combined with the clarity, portability, and reliability of our Class D Subway amplifiers. All in a lightweight, road-ready head that’s as easy to carry as it is inspiring to play.
