Hartke's KB12 Kickback bass combo amp is easy to tilt back for sublime clarity without floor rumbling -- making it a perfect choice for on-stage monitoring.

The classic Hartke Kickback 12 Bass Combo that has backed up bass pros in the studio and on stage for years just got better, a whole lot better! The new Hartke KB12 Kickback Bass Combo features the added muscle of a 500 watt Class D power amp and a premium 12" HyDrive speaker for extraordinary performance in a ruggedly portable, high power, tilt-back package.

The HyDrive Design

The KB12's 12" HyDrive speaker features Hartke's patented paper/aluminum hybrid cone technology for an exceptional blend of warmth and transient attack that can't be attained by traditional all-paper bass speakers. The use of rare earth neodymium magnets provides lightweight portability without sacrificing any of the legendary Hartke tone.

Shape Your Tone

Designed to produce a responsive bass tone that's both tight and warm, the KB12 preamp provides users with comprehensive tone control. Quickly dial in tone adjustments with the perfectly tuned 3-band EQ and Hartke's exclusive variable "Shape" circuit. When activated, the "Shape" knob varies the frequency range of a unique, fixed EQ curve that generates a dramatic variety of tone, color, and harmonics.

Kickback Versatility

In addition to sitting upright, the KB12 can be placed in the "kickback" position for better on-stage monitoring and clarity. The KB12 also features a headphone output for practice and a balanced XLR direct output to the mixer for live performance.

This is my first review of a product, but I felt it was worth it. I enjoy this amp. Small, compact, light weight, and has alot of punch. I went from a 78lb Peavy TNT 115. The lightweight 28lbs is a blessing. Yet with the DI and the fact it's a class D amp, I'm not sacrificing much. As with anything small I'm guessing I will have to watch how hard it is pushed, but so far it's not been nesessary.
Nice warm sound. Handles the low B on my 5 string. No need to push the volume.
Built in DI is great. Otherwise the rest is self explanatory.
Ease of Use
Super easy. The tech end is my weakness,so this amp makes it simple and effective for my needs.
So far so good. And it's size and weight make it real handy. Small enough to be put up front as a monitor, yet still delivers enough power and volume.
Little pricey but you do get what you pay for.

Haven't had to use as of yet.
The Wow Factor
Was completely shocked at the volume. Yet still produces a good solid sound. Have not used it in any large capacity as of yet, but with the DI should not be a problem.
