The Korg SP-170s is a digital piano that provides everything a pianist could want in terms of sound quality and realistic key action.  With this SP-170s digital piano, Korg has struck out to eliminate all of the unnecessary fluff of many digital piano and focus only on the vitally important aspects, such as key action and a nice realistic sound. In this Korg SP-170s review, we are going to take an in-depth look if this piano is for you.


The Look

As you can see, the design of the SP-170S looks simple.

The SP-170S is much smoother and beautiful than his older brother, the SP-170, and it comes with a black finish and it doesn’t have synthetic ebony/Ivory key top.

Since the SP-170S is a portable digital piano, there are a lot of bundles you can choose on the market, and some include the wooden stand.

Being a model released in 2010, the overall design is a bit outdated.

The SP-170S is compact enough to fit into smaller spaces.

The Music Rest of Korg SP-170S

Music Rest

There’s no change on the music rest about the SP-170s as it has the same design as the SP-170.

It is detachable and wide that it looks like a chopping board. But despite the look, you can display any score book or printed sheet music on it.

The only disadvantage of this music rest is that it has no comb-like stripes to prevent your sheets from sliding down.


For the SP-170s, it has two new button that they have added, and that is the sound and a piano play button. The rest is a power button and volume control.

For the Sound button, you will have access and select one of the ten keyboard sounds of the SP-170s, and for the Piano Play button, you can quickly select the piano 1 sound that is the default sound of the piano.

The only disadvantage for me is that it does not have an LCD display so that you will see the sound that you choose.

But all in all, it sounds good, and the buttons are easy to use.

The high-quality speakers of the SP-170s offer a reasonably spacious sound and give substance to the sound.
