Korg is well known for stage and portable keyboards, and they have a considerable presence in the digital piano market.

Before it was discontinued, the SP170s was one of our recommendations, thanks to its focus on what really matters - authentic piano playing feel and sound.

The keys are fully weighted like a traditional piano, where the higher note keys are lighter and gets heavier as you go lower. The ability to switch touch sensitivity lets you adjust the response of the keys to your liking, for a more personalized feel.

For adding realism and texture to the sound, the SP170 has reverb and chorus effects built-in. Teachers and students appreciate the two headphone outputs, and these can also be used to connect the unit to an amplifier or a PA system for live performance.

The Korg SP170s got a lot of kudos for its genuine piano sound, as attested to by both piano instructors and students who have tried it, and even the non-piano sounds were commended in some of the reviews. Playability was also well appreciated, inspiring some of the users to practice more and enjoy making music. There were many that found unit to be easy to use, thanks to its minimalist interface and streamlined profile.


While many loved the feel of the keys, there were some who noticed inconsistencies especially when playing hard or fast. A few users complained about the lack of a display area where you can monitor settings, while a few others found the volume lacking compared to other units of the same size.


Being from a trust worthy brand, it is an easy decision to give the Korg SP170s our thumbs up. It's difficult to find one of these available new these days, so to see our current recommendations please read The Best Digital Piano Keyboards.
