• Amp Bass Head Sm-1500 : Swr
Incredibly versatile, the SWR SM-1500 bass amp head from the Classic Series has two separate power modules providing an astonishing 1,500 watts (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 bass head will absolutely rock the house while providing the crystal-clear, full-range tone that the world's premiere bassists have come to expect from SWR.

In addition, SWR has added a popular Bass Intensifier circuit (a boost circuit great for soloing), and a tube-driven compressor, which can be engaged before or after the EQ section of the amp. The SWR SM-1500 is simply a remarkable piece of engineering as well as an incredibly powerful and versatile tool for the serious bass player.

True to SWR tradition, the SM-1500 is an innovative bass amplifier head that is the result of decades of research and design experience, coupled with direct input from the world's greatest recording and touring bassists.
