START WITH A GREAT SOUND TO DEVELOP YOUR TALENT
Buying the right amp when starting out in Music is one of the most important decisions both students and novices can make. Key to success is developing technique, along with refining sound preferences – including a responsive dynamic to their playing during practice. The CMB121 Black Line combo satisfies all these equirements, providing famous Markbass tone and response.

INEXPENSIVE, NOT CHEAP
This is the first time Markbass has focused on the lower end of the market. When we began, our main goal was to ensure you can buy something you enjoy the sound of. Almost all of our competitors build cheap equipment without considering that young and talented players who are going to use it every day may become frustrated and lose their passion due to a poor sound.
At Markbass we have always had a deep respect for all artists, beginners to professionals, and above all for young talent that strive to become the next generation of great artists. They need, and deserve a superb amp with superior sound – and our combo is the best choice!
