"The Markacoustic AC 101H is a simple and effective amp, its sound is deep and absolutely natural."—says Marco—"The two inputs are perfect to manage different situations, I think about a double bass and an electric bass (Channel 1 and 2), or just a double bass with two separate lines, pick up on Ch 1 and mic into the balanced input. Last but not least, the AC101 is light and portable."
