The MESA/Boogie B-800D is the Class D-powered re-imagining of the legendary B400+, blending its classic sound with the modern functionality of our successful Subway line.
This amp head marries the tube preamp architecture of the 400+ with the celebrated Boogie Channel topography from the Subway TT-800, then adds a dose of extra gain to unlock an even warmer, tube-enhanced character perfect for crafting subtle, musical overdrive. It delivers defined attack, clear pitch, and exciting dynamic content in a package that's ready for the modern stage.
