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.

 

Solid DI

 

Featuring a 1/4 "parallel output for dry signals, a 1/4" effect output for your amp, and a balanced XLR direct output, the Bass Attack 2 provides flexible output options for FOH or studio recording consoles. Its direct output Pre / Post switch allows players to adjust the stage sound without affecting the mix from the XLR to FOH. The Bass Attack 2 can also operate off of a mixer's phantom power via its XLR jack.
