Keyboard Amp Buying Guide 

Finding the best keyboard amplifier can be a difficult task due to the big market. 

Luckily, this buying guide will enumerate the essential factors you need to look out for when looking. 

Sound Quality 

The keyboard amp’s sound quality is the most vital factor you need to consider. 

What’s the point of purchasing an amp if it doesn’t provide you with crystal clear audio and a broad frequency spectrum? 

Sound quality is influenced by the speakers, sound processing choices, and the like. 


Speakers affect the sound fidelity; hence, you’ll need to pay attention to them. 

Your keyboard amp should come with a woofer and tweeter, at the very least. 

This combination produces a balanced response while simultaneously providing a decent frequency range. 

To increase the frequency spectrum, consider adding a midrange speaker or similar higher-output speakers. 

Some amps come with ports or strategically placed holes in the speaker for extended bass response. 

EQ and Channels 

The number of channels the keyboard amplifier dictates the number of instruments or equipment you can connect to it. 

Most keyboard amps come with two channels, while premium models have four channels. 

Each channel has its effect and volume controls, enabling you to adjust different instruments and equipment simultaneously. 

However, the more channels an amp has, the more expensive it will be. 

Built-in effects 

New keyboard amplifier models come with built-in digital signal processing (DSP) and sound effects. 

As such, you don’t have to purchase and invest in pedals, effect units, and the like. 

Effects usually include chorus, reverb, overdrive, but some amps offer more complex sound effects. 

If you often play live, choosing an amp with a built-in graphic equalizer and feedback protection system enables you to control your sound and enhance the overall performance. 

However, again, amps with more built-in features tend to run expensive. 


Keyboard amplifiers come with different wattage specs, which are: 

  • Peak watts refer to the max amount of power the keyboard amp can produce while it’s on a peak. The amp does not stay at peak level indefinitely since it can damage it. 
  • Continuous or RMS watts provide a more realistic way of measuring wattage since it looks at the amp’s average power output by measuring the RMS voltage. 

How much power you need will depend on where you will be playing. 

As a general rule, a high wattage enables the keyboard amp to amplify the sound with minimal distortions. 

If you play at larger or outdoor venues, then you’ll need a high-powered keyboard. 

On the other hand, if you play solo or at a smaller venue, then you’ll need less wattage. 

Inputs/outputs and stereo operations 

Having numerous inputs/outputs in your keyboard amplifier is also essential. 

XLR inputs enable you to connect microphones, whereas RCA inputs let you connect CD and MP3 players, and other similar devices. 

Meanwhile, XLR outputs enable you to connect to a PA system for live performances. 

Finally, headphone outputs are useful for indoor practices. 


Keyboard amplifiers are generally portable and are lighter compared to other similar music equipment. 

However, there are tiny keyboard amplifiers that are ideal if you want to carry them around. 

A keyboard amp with 8-inch speakers is ideal for beginners, while professionals should use at least 15-inch speakers.

What is the difference between a keyboard amp and a guitar amp? 

Guitar amps are designed specifically for guitars, enabling them to reduce bass and high frequencies and boost midrange tones. 

These amps also “color” the original sound, producing their distinct warm tone. 

On the other hand, keyboards can produce a broader frequency range. 

Hence, keyboard amps are more versatile since they usually have a woofer, tweeter, and midrange speaker. 

Because of this, using a guitar amp on a keyboard will be unsatisfactory as it forces the keyboard to lower frequencies. 

What is the difference between a keyboard amp and a PA system? 

Keyboard amplifiers and PA systems often share numerous characteristics like wide frequency range and EQ controls. 

However, these systems also have their differences. 

For one, keyboard amps are more portable than PA systems. 

Keyboard amps are more “all-in-one” units and come with wheels and handles for easy transportation and movement. 

Meanwhile, PA systems tend to be bulkier and contain more loose parts. 

Another difference lies in the number of inputs.  

PA systems offer more inputs, enabling the user to plug in and connect various instruments and other music equipment. 

This quality is what makes PA systems ideal for small bands and groups. 

On the other hand, keyboard amps are aimed at solo performers or those who perform in smaller venues. 

Are keyboard amps only used for keyboards? 

No, keyboard amplifiers provide a broader frequency spectrum. 

Hence, they can be used on numerous instruments like the acoustic guitar, drums, electric/digital pianos, synthesizers, etc. 

How much do keyboard amps cost? 

It depends on your budget. 

Keyboard amplifiers come in three price ranges: budget, mid-range, and premium. 

Budget keyboard amps cost less than a hundred bucks, making them popular among beginners or those on a budget. 

These amps can get you through performing in very small venues or during practices. 

Mid-priced keyboard amps are ideal for those who want to try their hand at performing before a small- to a mid-sized audience. 

They come with various connectivity options, enabling the player to hook up other equipment. 

Premium keyboard amps are the most expensive, but also boast the highest quality. 

As such, you often see them being used by professional keyboard players or those in a band.
