HARTKE HPBA 2



Bass Preamp / Direct Box



 with Overdrive

Overview

Back On Attack.

The Bass Attack 2 combines Hartke's classic preamp / direct box circuitry and striking tone into a rugged, zinc die cast stompbox-style design. Its ultra-clean, flexible output stage and vast array of tone shaping controls include 1/4 "and balanced XLR direct outputs and Hartke's legendary Shape EQ, Contour and Overdrive effect.

Study of Shape

Leveraging Hartke's years of experience focused on the needs of bass players, the Bass Attack 2 provides unique tone sculpting capabilities. The stompbox gives the player access to Hartke's Shape circuit, which activates a specialized preset EQ curve that can be customized using the Shape Frequency and Amount knobs. Players can also add a little extra color to the Bass and Treble knobs, along with the dedicated Contour switch.

Transient Attack

The Bass Attack 2's Overdrive circuit provides bass players with creative control over effects ranging from subtle tube emulation to grungy fuzz. The Tone knob lets you determine the perfect amount of high-frequency growl, while a dedicated knob manages the blend between distorted and dry signals.
