The Micromark 801 bass combo amp packs a punch but is still small enough to deliver the Markbass sound anywhere but big enough to provide a fuller sound with plenty of bottom end. The Markbass Micromark 801 features a single yellow 8 Markbass neodymium speaker. The original (6 ) Micromark has been astounding people since its first introduction a few years ago. But this new version is even more sonically impressive.
