Hartke KB12 overview

  • 1Description

Designed to tilt upwards on the stage if you should want it to—and thus, earning its name in the process—the Kickback KB12 from Hartke is a 500W combo amplifier intended for electric basses. It utilizes class-D amplification technology, and a 12" HyDrive speaker to deliver a powerful sound. The input jack can accommodate both active and passive basses, and the on-board three-band EQ will let you dial in a variety of tones, augmented all the more by the shape-control circuit. When engaged, this switch applies a 20 dB filter to a given frequency area adjustable via a knob to the right of the switch. The circuit is designed to further enhance your bass' tone.

This amplifier boasts both a headphones output for silent practice as well as an XLR output for feeding direct signal to the house, mixer, or recording interface. Should you wish to loop in an external 4-Ohm cabinet, you can do so through its 1/4" speaker jack on the rear. A built-in limiter protects both the speaker and the amp from overloads, and at approximately 28 lb, the amp is relatively portable and lightweight.

    Hartke KB12 reviews

    Kickback KB12 500W 1x12" Combo Amplifier for Electric Bass is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from A little sweetie The kickback- what an unbelievable amp. This thing put out like a teenager on prom night. I have used a Hartke 3500 for 19 years, traded it in and got another one, so I had no problem buying a Hartke.The new 3500 has 3-4 years on it, and is also cool. Those Hartke folks know how to build amps.The KB is a 12, and I was frankly surprised at what that baby can do. I used it for a gig, 3 piece band, plenty. I've also used it in church. Plenty. Just stick an XLR into it, send it out front, the soundman loves it.Not crazy about the filter thing, prefer running it with tone controls only,but that's up to the player. I like simplicity. If you want one, get it. No regrets.

    Rated 5 out of 5 by from Amazing Amp I took the kb to the gig thinking I'll just XLR to the fronts,btw, the amp has a ballsy output with the line send. Anywho, house guy says "we don't pump anything through the fronts. Cool. I used one 12" speaker and that Hartke, and sounded well baqlanced throughout the hall.Wow.I didn't think I'd get the clarity, but aluminum cones, yup, this is a keeper.

    Rated 5 out of 5 by from Absolutely what I needed I'm tired of hauling around my bigger 4x10 and 2x15 cabinets and Ampeg head. This combo is fantastic as far as sound power, tone and ability to plug directly into the house system. At 28lbs, it a dream come true.
