Genz Benz Amps - USED Streamliner 600 Head

SOLD - Contact us for more options

This Genz Benz Streamliner 600 Bass Amp Head is an incredibly large-sounding head in a remarkably small and lightweight chassis. Driven by three 12AX7 preamp tubes in an all-tube Class A, 300 volt preamp, it's got six separate gain stages and an intuitive interface that lets you easily manipulate and find your bass' tone. An elaborate, yet still simple tone network blends a modified passive Baxandall equalizer for the bass and treble with an active tube-driven mid filter. This allows for unwavering versatility that's capable of thick lows that don't undercut your natural tone, and crisp highs that aren't overwhelmingly sharp.

It's made with a CNC-machined solid billet aluminum faceplate for extra durability, and a brushed aluminum chassis finished in an anodized Gun Metal Blue color, so you don't have to worry about it being destroyed while on the road and between gigs. Like its name suggests, the Genz Benz Streamliner 600 Bass Amp Head is a streamlined approach to building your tone, and the perfect choice for some additional warmth or natural tube overdrive that rivals many classic tube amps, but at a fraction of the price and weight.
