Digital Piano Korg SV1 73 Full Review. Is it a good choice?

Korg Digital Piano SV1 73 Full Review. Good choice?

Korg is a Japanese company of electronic musical instruments and guitar tuners. And a few years ago (in 2009) it released a very interesting and vintage-style keyboard, we are talking about the Korg SV1 73 that had a price of about €1400, which in 2017 had a renewal and recently left the market, opening the way for the new Korg SV2 73, which we will also analyze later and it costs around €1.799/$2000/£1,666. Let’s go with the characteristics of the Korg SV1 73:

  • Vintage Aesthetics
  • 73 weighted keys (Weight that the keys of an acoustic piano have and that digital pianos try to imitate to equal the touch of the piano. The keys in the high register are heavier and in the high register less. This is different from the sensitivity on the keyboard which serves to regulate the volume of the note. But a weighted keyboard always has sensitivity in the keys) RH3
  • 80 notes of polyphony (Number of notes that can be played at once. This includes accompaniments that also consume notes. So if you play over an accompaniment more notes will be accumulated)
  • 36 sounds (Different sounds of piano and other instruments)
  • 8 sensitivity and speed curves
  • Tuning and Transposition function (Transposition allows you to move the note spectrum of a keyboard. This is to be able to play with transposing instruments. It is not an easy concept but it is made to facilitate the writing of an orchestration for instruments with very different bass and treble registers)
  • Enhanced Definition Synthesis sound engine and Real eXperience technology
  • 8 memory spaces for saving favorites and settings
  • 1 x 12AX7 valve on the preamp
  • 36 demo songs
  • Sustain pedal (The sustain pedal on a piano or keyboard is used to keep the note playing even if you stop pressing the key) type Korg DS-2H
  • Hull exit
  • JACK and XLR line input and output
  • Midi input and output (MIDI allows you to do such wonderful things as connect your keyboard to your computer, record a sound track, and with certain programs click through what you’ve played to musical notes on a score. MIDI tracks store the information of the musical notes)
  • USB to connect pendrive
  • It has a lectern and a network cable
  • a weight of 17.5kg and a size of 1143 x 347 x 154mm

demo review korg-sv1-73

Now two videos about the Korg SV1:

We have a keyboard with a vintage look that has very good features, such as its weighted keys, its excellent sound quality is something very uncommon in keyboards, vacuum valve for the preamp part, this is only seen in electric guitar amplifiers, however the Korg company has bet on this kind of effects.

Now let’s compare the Korg SV1 73 with its more common alternatives. Also at the end of the post you will find a section with the best purchase possibilities for this keyboard. But you can go directly to that part of the post by pressing the next button.

Now let’s compare the Korg SV1 73 with its more common alternatives. Also at the end of the post you will find a section with the best shopping possibilities for this digital piano. But you can go directly to that part of the post by pressing the following button.

Korg SV1 73 vs Korg SV2 73

As we mentioned before there is a new version of this same model that has a higher price with almost 400 euros more and now we will see face to face with the characteristics of each one:

  • Both keyboards have 73 speed-sensitive and weighted keys. Let’s remember that sensitivity refers to the fact that we can play our performances with dynamics, that is to say, when a key is pressed with force it sounds higher while when a key is pressed with less force it sounds lower. And weighted keyboard refers to the weight that the keys of a real acoustic piano have, in the high range with lighter keys while in the low range, the heavier ones.
  • The SV1 has 36 sounds with 80 notes of polyphony, while the SV2 has 72 sounds and 128 notes of polyphony.
  • They have the same sound engine and the same sound functions so they also have the option of the valve circuit, with the 12AX7 in the preamp.
  • The SV2 has the sounds of four concert grand pianos and two upright pianos, as well as input for three pedals, when the SV1 only had 1.
  • The SV2 offers 2 unbalanced XLR line outputs / 6.3mm jack and 2 unbalanced 6.3mm jack line inputs when the SV1 offered one of each.
  • The Sv1 weighs 17.5kg and measures 1143 x 347 x 154mm and the SV2 weighs 17.2kg and measures 1143 x 157 x 347mm (W x H x D), being almost exactly the same in this respect.

There are many improvements in front of the new generation, and because of the increasing value it is worth going to the next level.

Korg SV1 73 vs Clavia Nord Stage 3 88

We will now have the following comparison: The Korg SV1 73 keyboard with a price of approximately €1400 and the Clavia Nord Stage 3 88 with a value of €3.490/$4500/£3,185, almost doubling the value of each other. With such a big difference in price we will analyze their differences in functions and features in the following face-to-face:

  • Starting with the keys, the Korg has 73 weighted, touch-sensitive keys. The Nord has 88 weighted touch-sensitive keys. Remember that sensitivity means that we can play our performances with dynamics, i.e. when a key is pressed with force it sounds louder while when a key is pressed with less force it sounds lower. And weighted keyboard refers to the weight that the keys of a real acoustic piano have, in the high range with lighter keys while in the low range, the heavier ones.
  • The Korg SV1 has 36 sounds with 80 notes of polyphony, while on this Clavia Nord it has 2Gb of storage for sounds from its library, which is actually very extensive and 120 notes of polyphony.
  • The functions that characterize the Korg SV1 are: 8 sensitivity and speed curves, Tuning and transposition function, Enhanced Definition Synthesis sound engine and Real eXperience technology, 8 memory spaces to store favorites and settings and a 1 x 12AX7 valve in the preamp.
  • The Clavia Nord Stage 3 features: String Resonance function (Gen 2), Noise Pedal and Long-Release option, powerful synthesizer capabilities with Subtractive Synthesis, FM, and Wavetable, Arpeggiator function, has Master Clock and Unison modes, includes modes for the famous B3, Vox/Farfisa and Main Pipe organs very similar to the original, also simulates the Leslie Vintage 122.
  • The Korg has: Korg DS-2H type sustain pedal, headphone output and JACK and XLR line input and output, while the Nord has: 4 assignable audio outputs Jack, Stereo Headphone Jack output, 1 mini-jack monitor input, input for sustain pedal that supports triple pedal, input for rotor jack pedal and also supports organ, switch and control pedal with stereo jack, plus a network cable. A great advantage over the Korg.
  • Both have MIDI in and out and USB MIDI that allows them to be connected to a computer for use in a music production program.
  • The Sv1 weighs 17.5kg and measures 1143 x 347 x 154mm and the Nord weighs 19kg and measures 1287 x 334 x 118mm (width x height x depth), which is almost exactly the same in this respect.

As we can see in many ways if not in all the Nord has an advantage over the Korg, not for nothing this is one of the most sold and purchased by professional musicians, it is very common to find these teams in a music video both for its sound capabilities and for its special design. Logically, it is worth what it costs and it is not cheap compared to other models. Even for a tighter budget the Korg is not a bad option.

We will put the characteristics of each of these pianos in 2 different columns to make it easier to see the differences:

Korg SV1 73 vs Korg Grandstage 73

Again, we will analyze two Korg keyboards, having a fairer comparison: The Korg SV1 73 keyboard that we have already mentioned has a price of about €1400 and the Korg Grandstage 73 that has a price of €1.599/$1999/£1,499, being about €266 cheaper the first one. We will analyze their differences and similarities in the next section:

  • Both keyboards have 73 speed-sensitive and wighted keys. Let’s remember that sensitivity refers to the fact that we can play our interpretations with dynamics, that is to say, when a key is pressed with force it sounds higher while when a key is pressed with less force it sounds lower. And weighted keyboard refers to the weight that the keys of a real acoustic piano have, in the high range with lighter keys while in the low range, the heavier ones.
  • The SV1 has 36 sounds with 80 notes of polyphony, while this Grandstage has 500 sounds, including 5 grand and several upright pianos and 128 notes of polyphony.
  • The SV1 has the Enhanced Definition Synthesis sound engine and Real eXperience technology, while the Grandstage has 7 sound engines. Giving a great advantage to the second one.
  • The Grandstage has a modulation wheel, a pitch bend wheel and a sustain pedal and input for three pedals.
  • The Grandstage offers 2 balanced XLR line outputs / 6.3 mm jack balanced and 2 unbalanced 6.3 mm jack line inputs when the SV1 offered one of each.
  • The Sv1 weighs 17.5kg and measures 1143 x 347 x 154mm and the Grandstage weighs 17kg and measures 1099 x 359 x 140mm (W x H x D).

Again we find two good keyboards, with some difference between them. The Grandstage has a greater amount of sounds and polyphony notes as well as having more sound engines. The SV1 has certain features such as Enhanced Definition Synthesis and Real eXperience technology that give it an edge, aside from its valve circuitry. It’s actually a bit of a complicated decision, but a lot also depends on what you’re going to use the keyboard for.

We will put the characteristics of each of these pianos in 2 different columns to make it easier to see the differences:

Korg SV1 73 vs Clavia Nord Electro 6

As a last comparison we will have the Korg SV1 73 keyboard that we have mentioned has a price of about €1400 and the Clavia Nord Electro 6 that has a price of €1.769/£1,599 with a difference of about €230:
