A2BP pro MARK II

The ALBIT A2BP pro MARK II is a 2-channel bass preamp pedal engineered for flexible tone shaping and expanded connectivity. This updated version drives vacuum tubes at high voltage, delivering tube-driven preamplification, with each channel featuring a distinct EQ configuration: Channel A retains the original tone circuit, while Channel B uses the advanced tone circuit from the A1BP pro MARK II. Both channels provide a flat frequency response with tone controls set to center. The traditional mute switch is now a footswitch, enabling hands-free operation. The BALANCE VOL control allows separate level adjustment for the balanced (BALANCE OUT) output, independent of the MASTER volume. An AUX IN input has been upgraded to a 3.5mm jack for broader device compatibility. **Key Features:** - 2-channel bass preamp pedal with tube-driven circuits - Distinct EQ circuits on Channel A and Channel B - Footswitch-activated mute function - Independent BALANCE OUT volume control - 3.5mm AUX IN jack - Flat EQ response at center settings on both channels
