I remember the time I was first introduced to keyboards. My close friend was saving up for a couple of months, praying for the mercy of gods and relatives and finally got his hands on his first keyboards. We were both so excited to dive in, try various things out and explore all of its functions and capabilities. We basically bothered every single neighbor, since nothing we played sounded any good. But as I spent more and more time with this instrument, I fell in love and have been its loyal customer ever since.

Through all these years of performing, creating new pieces and developing my craftsmanship, I encountered numerous amplifiers with both good and bad experiences. And somewhere along the way I came across Peavey KB2. At the time, I was sick and tired of huge and loud combos, since I had taken my music from stage to home and studio. I was in need of a small keyboard amp that would simply understand what I wanted and reproduce my desires faultlessly. Luckily, Peavey KB2 did exactly what I asked for and continues to do so even now. If you are in search for anything resembling what I have just described, stay with me as I introduce this product to you.  


There is one persistent pattern connected to Peavey: no matter in which price range their amplifiers fall into, the quality and feature set remain the same. What I mean is that they do not usually botch cheaper models and pay a lot of attention to their construction. KB2 packs everything a keyboardist will ever need and a tad more. Its output power is bi-amped and offers 45 and 12 watts.

It drives a single 10” coaxial speaker guarantees accurate response in all frequency ranges. It comes with 4 channels with individual inputs and accepts various instruments, including acoustic and electric guitars. You can also plug in the microphone and sing along your beautiful keyboard lines. Three of these channels have dedicated equalizers that make tone shaping easier and allow you to tackle unpleasant sounds more precisely. Additionally, Peavey KB2 has an in-built effects loop for those of you who love to employ audio effects in their performance and spice things up a bit. This combo can be utilized for recording, stage monitor or a simple practice tool.

As far as the connections go, this bad boy has ¼” inputs for high-impedance units on channels 1, 2, and 3. The latter also has XLR balanced input for low-impedance microphones and other devices of the same ilk. Channel 4 has monitor input that can be connected to the output of any line-level unit. KB2 also has Line Out jack that can be plugged in with a mixing console or a recording apparatus, effects loop Send and Return sockets and a headphone output.


Peavey had simplicity in mind when it was putting together the control section of KB2. Figuring out the functionalities of the available knobs is a child’s play and requires a small amount of time.

The layout is split into four different sections according to the channels. Channel 1 and 2 have Level, Low and High controls, Channel 3 has Level, Low, Mid, and High controls, while Channel 4 has only a Monitor knob. So, Level encoders here modify the volume of incoming signals, Mid, Low and High alter the amount of specific frequencies, while Monitor acts as a level control and sets the volume of the CH4. And that’s it. These couple of knobs are the only things you will have to mess with during your utilization. As you can see, the control section of Peavey KB2 is truly simple and easily configurable.

Peavey KB2 Sound

When I mentioned that Peavey KB2 could be employed with almost any instrument, I was not exaggerating. Even though it specializes in keyboards, it performs wonderfully with basses and guitars as well. This makes it so much more versatile and forces you to grab different instruments to experiment with. But when it comes to keyboards themselves, KB2 shows off all the best qualities. It can create pristine cleans and does not get distorted even at maximum settings. This way you can crank up the volume to the fullest and conquer the venues you are in. Speaking of the venues, this combo can be quite loud compared to other models of the same measurements. This is due to the bi-amped design which enhances the output without adding any additional watts. What is more, KB2 has defined and articulate sound that can be tweaked interminably through individual EQs on the channels. And let’s not forget the vocals that have wonderful output through this amplifier as well. The in-built effects loop allows you to connect your pedals to the rig and explore the territory of audio effects. This way you can add some texture, shape and dimension to your tone, but still maintain the character of your instrument. It can be used as a portable PA system as well, if desired.


Taking into account everything together, judging by features, controls, and sound, considering the price and dimensions, it is clear as a day that Peavey KB2 truly rocks. The versatility this fella offers is out of this world and the sound (uh, the sound) it can produce is spectacular. It is hard not to fall in love with the character of this amplifier because every note it delivers is scrupulous and well-structured. It will not color your keyboards by any means, but it will accentuate its nature and make it more prominent. Peavey KB2 will be the best friend for budget players, professionals, beginners, and basically anyone who wants to possess a badass combo. If you have not tried it out yet, what the hell are you waiting for? Good luck!
