Peavey KB Series "KB1" Keyboard Amplifier 20-Watt 1x8"

The Peavey KB1 is perfect for practice, pre-gig warm-ups, songwriting or any application where quality sound is important, but a large, bulky unit is just too much.

The design of the KB1 makes it a compact workhorse amplifier for keyboardists, acoustic guitar players and other musicians needing full-range output in a small package. At 20 Watts RMS, the KB1’s heavy-duty 8" speaker gets the job done! And for situations that require headphones, the KB 1 delivers.

Two channels are provided, featuring 1/4" inputs, level controls, and two-band active equalization (Low, High). The front panel headphone jack automatically disables the internal speaker when connected. Special attention was given to make the KB1 as compact and light as possible to maximize portability, yet provide a "big" sound. Go ahead...pick it up! At 17.4 lbs., it’s perfect for "on-the-go" projects. And the size? Well, let’s say it’ll fit just about anywhere.

Like all of the KB Series, the KB 1 is built for the road. First, extremely tough black covering is provided along with heavy-duty corners. Second, a serious handle is available at the top of the unit. Third, a heavy-duty metal grille is provided to protect the speaker.
