    Unveiling of the WD-800 in direct response to player feedback and the longstanding demand for a more powerful version of MESA/Boogie's WalkAbout™ Bass Head. This Head combines the warm, soulful sounding magic of the WalkAbout tube preamp section with the musical Class D Output Power used in our Subway Line (D-800™ and D-800+™), to create the ultimate lightweight hybrid.

    As in the original, the inspiring round, fat WalkAbout Tone is joined by comprehensive rotary shelving Tone controls and a semi-parametric EQ, giving you total shaping authority in the preamp. The new WD800 also features the Subway D800 Plus’s highly effective HIGH PASS FILTER and a new POWER AMP DAMPING control, which allow tuning of the sub-low frequencies and power response options respectively. The POWER DAMPING choices enable you to tailor the tracking and feel of the power amp. The LOW setting produces a looser, more relaxed and blooming character reminiscent of Tube power. HIGH tightens the low end, adding punch and accuracy in tracking, while MEDIUM provides a blend of these opposite ends of the power response spectrum.

    The WD-800 can perform as a stand-alone Head or be mounted in 2 Spaces within standard 19” Racks by attaching the optional Rack Ears (not included). Whether you’re looking for a lightweight new main rig to replace your heavy linear amp with a bigger, wider sound and more complex harmonic content than the lightweight options you’ve tried, or just a compact, portable head for everyday gigging and recording that will fill the room with luscious Tone, the new WD-800 covers bases with power and versatility to spare. Not exactly a WalkAbout or a Subway, but rather everything great about both combined in a super-responsive compact, lightweight, big-power platform, just as you ordered!
