Final Thoughts

Deciding what you want when buying your new keyboard amp can be a tricky business, and there’s no point starting to look if you don’t know what you want. Luckily, this guide is here to take you through some of the things you need to be aware of before you buy it.

First off, knowing what you're buying is probably a good idea. For example, it’s worth knowing that the amp you buy won’t just work for keyboards but a large variety of other instruments too. They are referred to as keyboard amps because of the sonic range the amp is capable of providing. The sonic range covers bass, higher-pitched instruments, drums all sorts. The actual ‘amp’ you buy, is really a pre-amp, a horn, megaphone, and speaker all in one box. Good keyboard megaphone can reproduce the sonic range of every instrument accurately which is why it's called a keyboard amplifier.

But really what is that makes a keyboard megaphone different from other amps? Well a keyboard megaphone is designed to sound big on stage because of the low-frequency sound output on the basslines. But the same amps can also play crisp high frequency for high notes. They promise low distortion and flat frequency and less feedback. A keyboard megaphone is also equipped with two or three inputs, so you can connect multiple instruments up at the same time, and every channel has its own preamp. A guitar amp on the other hand can only hold up one guitar at a time. So you can see why a keyboard amp is entirely different from a guitar amp.

One of the first things you need to decide is how much money you’re looking to spend. Higher-end amps might be more-high powered, and they’ll provide separate controls for equalization on each channel, but that doesn’t mean that there aren’t more budget-friendly amps that could give them a run for their money. You need to think about what’s important for you and prioritize to make sure the amp you buy is the best one for you. If you have an expensive keyboard then maybe it's better for you to choose a proportionally priced amp - otherwise a cheap amp could really devalue the quality of your keyboard sound.

You need to think about the power and the size of the speaker you want. If this is your first speaker you’re not going to need more than 50-watts of power and an 8-inch speaker because you’re probably only going to be using it for practice, at least to start with. You need to analyze your needs, and look at size and power according to what you’re going to be using it for. There’s no point in forking out for something powerful when you’re never going to use it to its full ability.

If you’re going to be playing with other people then look at the number of channels you have, and the amps ability to connect up multiple instruments, and how those channels are controlled. Do they have separate controls for each channel, and is this something you need? If you’re going to stream something external then you need an AUX port. It’s worth noting here that not every amp will have these things and checking out features that the one you want has, is always a wise idea.
