Just found this in my basment and totally forgot I had it. Its only been used a handful of times so it's basically in perfect condition. Asking $350 or best offer. "The HA4000 provides 400 watts of power into 4 ohms and it also provides a number of advanced features, such as parametric equalization and a dedicated subwoofer output. You'll find the HA4000 to be an ideal bass amplifier for live performance use in medium and large-size venues and in recording environments as well."
