OWNER'S MANUAL
1. Introduction
Congratulations on purchasing one of the world's best acoustic guitar amplifiers! Markbass amps are built to the highest standards by a small team of skilled
technicians in San Giovanni Teatino, Italy.
We have spent many years researching not only the highest-quality technologies for amp design and construction, but also the practical needs of the working
acoustic guitarist. The end result is a product that combines outstanding sound quality with intuitive features, attractive design and extreme reliability—all
in one impossibly lightweight unit. This amp will allow your instrument to speak in its natural voice, faithfully conveying your musical ideas to your audience
with stunning clarity.
Your amplifier has passed rigorous product testing and should survive even the toughest of environments on the road, in clubs, rehearsal halls and concert
stages. Nonetheless, please treat it with care and you will be rewarded with many, many years of glorious, rich, powerful tone!
If the clarity and power of this amp inspire you to play better music, we will have succeeded in our mission. Good luck and enjoy your new best friend!
Sincerely,
Mark Acoustic
