I expected top-notch tine electric piano sounds and they are great. FM pianos, strings/orchestral sounds are better than I expected. Reed electric pianos are also good. Acoustic pianos with warm character. Many "hidden" sounds which you can access via editor, much more than 72 panel sounds!
Strengths:
- all built-in sounds are even, good quality
- one of the best of hammer-action key actions in 73/76-key boards, in any price range (Korg RH3), has long pivot length for a digital instrument
- great possibilities of sound editing - with hands-on panel knobs and buttons and much deeper via editor
- totally seamless transition between presets (when volume levels are same and amp section is off)
- instrument is sturdy (metal housing, MDF bottom, cheeks are plastic but appear sturdy, too) and unique looking
Little weaknesses or limitations:
- DS-2H sustain pedal could be higher quality (its housing), but works well, there is also possible to use DS-1H as alternative
- sound transition from one preset to the other is not so seamless when volume levels aren't same (but the sound does not cut out like in some other instruments!)
- layers of sound are routed to the whole effects chain, not individual effects, so you cannot put different effects on different layers, but you can bypass a whole FX chain on layers individually. It is enough for most situations.
If those little limitations aren't deal-breakers for you, I strongly recommend SV-2 as simple to use and very warm sounding stage piano, oriented for classic and vintage sounds - tine pianos in particular.
