The Streamliner™ STM-900 bass amp head from Genz Benz boasts a 300-volt, all-tube Class A preamp driven by three 12AX7 preamp tubes utilizing six gain stages. The STM-900's preamp design features an intuitive and highly effective tone network which is a unique blend of a modified passive Baxandall network for the bass and treble along with an active, tube-driven mid filter with selectable mid frequencies. The versatile all-tube preamp exudes a fat and rich tone that remains articulate. It can be used to simply add warmth to your natural tone or it can be dialed in to provide a wide range of natural tube overdrive.

The Streamliner™ 900 also features proprietary 3 Dimensional Power Management analog technology that adds heft and girth to each individual note while enhancing the amplifier;s responsiveness and headroom. It provides the dynamic and three-dimensional tone and feel of an all-tube power amp design.

With its solid extruded aluminum panels, CNC machined solid billet aluminum faceplate and smooth-radius edges the Streamliner™ 900 chassis emanates the ruggedness and strength of a world-class touring machine. This brushed aluminum chassis is finished in an anodized Tungsten finish.

The powerhouse behind the Streamliner™ 900 is a Class D amplifier and SMPS module, enhanced with patent-pending P.H.A.T. (Proprietary Heat Abatement Technology) topology. This delivers robust and reliable, high output performance in a tremendously compact and convenient package.

Simply put, the new design of the STM-900 offers a more streamlined approach to finding your voice, yet it still carries forth the GENZ BENZ reputation for performance, reliability, and innovation.
