The Hartke KB12 Kickback Bass Combo doesn't care if you're headlining a festival or playing to a room of twelve people who came for the free nachos — it brings the same 500 watts of thunderous, focused bass tone either way.
Built around Hartke's legendary HyDrive speaker technology and a featherlight Class D power amp, the KB12 is the kind of amp that earns its spot in the van and never gives you a reason to regret it. Rugged, portable, and packed with tone-shaping tools that actually make a difference, this combo redefines what a professional bass amp can fit into 28 pounds.
Bass speakers have long been forced to pick a side — warm and round, or punchy and articulate. Hartke's HyDrive technology refuses to choose. The KB12's 12" speaker combines a paper/aluminum hybrid cone with a rare earth neodymium magnet, giving you the full-bodied warmth of paper and the fast, clear transient response of aluminum — simultaneously, without compromise. It's the kind of tone that makes sound engineers nod in approval and other bass players ask uncomfortable questions about your gear.
A bass amp with real power used to mean a real workout. The KB12 flips that expectation with a lightweight Class D amplifier pumping 500 watts of output — enough headroom to cut through a loud band, hold the low end in a live venue, and still keep the whole rig under 30 pounds. It's the rare piece of gear that impresses your ears before it destroys your back.
The KB12 gives you a full 3-band EQ plus Hartke's exclusive variable Shape circuit, letting you dial in everything from tight and punchy to wide and harmonic without guesswork. Add to that a tilt-back cabinet design that angles the speaker directly toward your ears on stage, and the KB12 becomes the kind of amp that actually works with you instead of just sitting there looking good.
The KB12 Kickback Bass Combo is built for bass players who need professional tone, real power, and genuine portability — without having to choose between them. Between the HyDrive speaker's hybrid cone technology, the muscle of a 500-watt Class D amp, and a tone-shaping preamp that handles everything from subtle warmth to serious color, the KB12 shows up ready for whatever the gig demands. If you've been searching for a bass combo that punches well above its weight class and fits in the back of a hatchback, the Hartke KB12 makes a very strong case for itself.
