The Markbass CMD 151P is a bass combo amplifier equipped with Markbass' flagship solid state preamp, the Little Mark II. Despite being a Mini model, the CMD 151P amp gives you maximum power and sound. The amp provides plenty of power to blow through the high-quality 15" B&C woofer and piezo tweeter. The CMD 151P also has 2 speaker outs which allow you to hook up to another 8 ohm extension cab, giving you a 500W rig! The Little Mark II has a 4-band EQ, as well as two exclusive Markbass' filters for rounding out your tone to perfection. A handle on top makes Markbass CMD 151P amp easy to transport too.
