Top Italian session bassist Paolo Costa has teamed up with Markbass to design a high-quality bass preamp for both studio and live applications. It's the perfect studio tool for recording bassists, combining two channels, "clean" and "amp": CLEAN is a pristine direct channel which features a Pure Parametric Filter EQ for fine-tuning your sound to perfection. The AMP channel provides three types of distortion (two tube-driven and one solid state) to mix in with the clean channel. Personalize your sound with precision with two more EQ controls, variable pre-shape filter (VPF) and high pass filter (so you can apply distortion to only the high end), and push-pull knobs give you the ability to store your distortion settings. The professional compressor on the amp channel helps you tame the edges. The preamp's back-end offers three balanced XLR outputs so you can record each channel separately or together. An indispensable addition to any recording bassist's gear arsenal!
