I was very impressed with the construction of both the G70 & PA1X when we attended a recent 7 night keyboard festival.
The Guitar Mode on the G70 is a very nice useful feature. It's interesting to note that all these extra features added to v2 are FREE OS update. Optional is a plug-in board containing new styles & voices at £199. This is a little different to having to pay out £1500 to change T1 for a T2.
We have to admit that Roland just did not get the G70 as it should be when launched, but the dems I experienced during our week on G70 v2 by keyboard player Ralph Shink were excellent. What a lovely keybed feel to play.
