MESA/BoogieBass 800D 800W Bass Amp Head

The MESA/Boogie Bass 800D 800W bass amp head reimagines the legendary Boogie 400+ for a new era, delivering its unmistakable warmth and dynamic punch in a format that’s lighter, more portable and perfectly suited to the needs of modern bassists. Built in Petaluma, California, this hybrid design pairs a tube preamp with Class-D power, producing up to 800 watts of bold, articulate tone that thrives onstage or in the studio. With thoughtful updates inspired by MESA’s acclaimed Subway line—including intuitive voicing switches, an onboard high-pass filter and versatile connectivity—the Bass 800D bridges the gap between vintage tube character and cutting-edge performance, all in a rugged chassis that weighs just 6.7 lb. Classic Boogie Tone With Modern Efficiency At its heart, the Bass 800D draws directly from the heritage of the iconic Bass 400+, a tube-driven powerhouse beloved for its rich harmonic content and commanding low end. The single 12AT7 preamp tube captures the warmth and natural compression of MESA’s tube lineage, while Class-D power delivers tight, immediate response with massive headroom. This hybrid approach provides the best of both worlds—supple dynamics and tube-enhanced overdrive when you want it, paired with the speed, punch and accuracy that only modern Class-D amplification can achieve. The result is unmistakably Boogie: big, bold and ready to lead the band. Streamlined Controls for Immediate Tone Shaping Rather than a sprawling graphic EQ, the Bass 800D emphasizes simplicity and effectiveness, offering controls that matter most to working players. Switchable low- and high-gain inputs let you tailor your response to your instrument and playing style, while deep and bright contour switches quickly expand your tonal palette. The onboard high-pass filter provides precision control over sub-lows, tightening up your mix and preventing mud onstage. Combined with traditional bass, mid, treble and master controls, the Bass 800D makes it easy to dial in a polished, professional sound—whether you’re chasing vintage roundness, modern snap or something in between. Versatile Connectivity and Pro-Grade Features The Bass 800D is designed to be as versatile offstage as it is on. A balanced XLR direct out with pre/post EQ switching, line/mic level and ground lift provides reliable connection to front-of-house or recording interfaces. An auxiliary input and headphone jack make silent practice a breeze, while the fully buffered effects loop integrates seamlessly with pedals and processors. For gigging musicians, the inclusion of speakON speaker outputs and a comprehensive impedance selector (2, 4 or 8 ohms) ensures compatibility with a wide range of cabinets. Add in a USB power port, tuner out and remote mute jack, and the 800D is as practical as it is powerful. Lightweight Build and Road-Ready Reliability Weighing in at just 6.7 lb., the Bass 800D is built for effortless transport without sacrificing durability. Its rugged aluminum chassis is powder-coated for maximum protection, while fan cooling ensures reliable operation in demanding environments. The universal auto-configuring power supply adapts globally, making it a trusted companion for touring bassists. Paired with the included gig bag and optional footswitch, this compact powerhouse is engineered to handle the grind of modern gigging life, all while delivering the unmistakable MESA voice night after night.
