The SM-1500 bass head is the new "flagship" amplifier in the SWR® line of high-quality, professional products for discriminating bassists. This amplifier is incredibly versatile, with two separate power modules providing an astonishing 1500 watts of power at 4 ohms in the bridged mono mode - or 750 watts per side in either stereo or dual mono, an onboard tube-driven compressor, and an array of tone controls that would be right at home in the world's best studios. The SM-1500 will absolutely rock the house, but will still provide the crystal-clear, full-range tone that the world's premiere bassists have come to expect from SWR.
