Brought over my image from the post on SLG130 NW for your reference. Left is SLG200N and right is SLG130 NW. Hope this helps.
How does it sound live?
This is a "dead" electronic instrument. It does not have a live wooden sound box to complement and project the voice naturally. So, its sound depends on the amplifier used and positioning (sound system setup), and expensive cable may believe by some for enhancement. Plus, it breaks the sound barrier of a normal CG in a live concert, just like an electric guitar.
You do a quick search in youtube and listen to its sound sample played by many performers. It is exactly what you will get.
How does it feel?
It is very playable. Good low but no buzz set up, slightly narrower fingerboard like most Yamaha CG, very gentle for smaller hand. Quality and built is of good Yamaha standard.
However, as mentioned in the other post, the back of its nature finished fingerboard is not very smooth as per Yamaha GC or even CG range. I suspect this maybe due to the natural grain of wood used, not workmanship or quality.
Next is the contour of the body side edge (see picture). It is not very gently rounded, but almost square. It hurts the chest and arm during long duration playing, but adding some cushioning will solve it.
For me, SLG works very very well as a practice guitar. I can play hours now without a single complain from my family on the noise (to them) except the time that i have spent on it.
Personally, I also like the feeling of nature finished fingerboard from the new Yamaha range since they have introduced few years back. Not forgetting its built in tuner, which is just another bonus that I'm enjoying.
Without heart and desire, talent is nothing.
