I have had both units....
in it's day the G70 held it's own....
with many ground breaking features
But as we all know technology waits for no man
The New Genos is light years ahead of the
much older G70 in today's world of arranger kb technology..
but still very usable in many ways, but not many even have them anymore.
Discontinued models are difficult to find parts for, etc,..
More for home or studio due to their weight
then a every day in & out gigging kb..
