The MESA/Boogie Bass 800D brings the legendary tone and feel of the iconic Bass 400+ into a modern, compact Class D design. Delivering 800watts of pure power, this lightweight head captures the warmth, punch, and responsiveness of the original valve architecture while incorporating the precision and efficiency of contemporary Class D amplification. With a redesigned valve preamp inspired by the 400+ and the Boogie Channel topography of the Subway TT‐800, players can achieve rich, dynamic tones ranging from clean articulation to smooth, musically rich overdrive.
The Bass 800D replaces the traditional 7‐band graphic EQ with intuitive front‐panel voicing options, including LOW/HIGH gain, DEEP, and BRIGHT switches�each with bypass functionality�allowing quick access to professional‐grade tones without complex adjustments. The addition of a HIGH PASS rotary control provides further flexibility, enabling players to fine‐tune their low‐end response and maintain mix clarity even at high volumes. Built for reliability, it features a 12AT7 valve preamp tube, rugged chassis construction, and advanced DSP management for consistent performance across all playing environments.
Practical enhancements include dual speakON® locking outputs, selectable 2/4/8Ohm impedance for cabinet flexibility, headphone and AUX inputs, a USB device power jack, and a remote mute trigger. Combining heritage tone with modern control and portability, the MESA/Boogie Bass 800D is the perfect head for discerning bassists seeking a powerful, road‐ready amp that delivers authentic valve warmth and contemporary versatility.
