Vano Hi!
I have not played the G-70 but from your post I think you may have different requirements in a keyboard than many of us in this forum. Certainly, to me at any rate,
"drums and basses" are not the most important features, rather the quality of the overall instrumental and solo voices together with the ease of operation and quality of construction. From what I have read of others who HAVE used the G-70 it seems that it scores quite well on most aspects.

Maybe some other brand will be a better buy for you.
