Bass Attack Introduction and Features

Introduction

Wow Man! You just bought the coolest and most useful tool a bass player can own, the
Hartke Bass Attack! The Bass Attack is a serious pre-amp and DI that provides dual func­tionality by incorporating great front-end tone shaping, along with a super-clean balanced
direct output to send to your recorder or Front-Of-House mixer. You can dial-in a wide
range of sound, thanks to Hartke’s VXL Tone-Shaper circuitry, which features a powerful
three-band equalizer, plus a Harmonics control with Mix that lets you add a little bit of
warmth, or all the way to complete grung. You also get the world famous Hartke Shape
circuit that will enable you to further control your tone and get the sound that’s just right for
your music. If you’re playing live, you can take advantage of the two footswitches that let
you change your sound by engaging the Shape or Harmonics. The Bass Attack has
extensive input and output connectors including 1/4-inch inputs, balanced XLR Direct
Output and 1/4-inch Parallel Output, providing maximum flexibility for patching in to amps,
mixer and recorders. The Bass Attack is perfectly at home in the studio or on the road. In
fact, the aluminum extrusion and steel chassis ensure solid performance from night-to­night and venue-to venue. Whether you are recording or playing live, the Bass Attack by
Hartke will give you the sound you’ve been looking for.
