Hi Scott,
The first "Y2K" I bought I had to return. That was in "Jan." The problem I had was "very poor" action of the "dimple-switches" have had "Yamaha" KB in the past I knew what to look for and they just didn`t "feel-right"
Also there was a "louder than Amp" noise (hiss) comming from the speakers even when there was NO volume
And last (I think because of the dimple problem) some of the "LED`s" would "flicker" even though they were off or not in use.
After waiting and looking for another KB and reading the "post" here at the "Zone" I decided to try another "Y2K" , (In mid to late Feb.) but only from a place where I knew I could get a Full -Refund if it didn`t work out.
So far (knocking on wood) my 2nd "Y2K" has held up.
The dimple switches have a more "tactile-feel" and there is a "hiss" but no where near as bad as the 1st (this one just "amp-hiss")
And although there are some "LED`s" that flicker when they shouldn`t, it so far has not been a major issue in the performance of the KB, (not as many "flicker" )
Overall I wish it was built better. In the past they have made "better quality" portable KB`s and there is realy no excuse for the "shoty-workmanship" in the "Y2K" except , fo course to save them (Yamaha) money and leave it`s customers wondering why.
Would I buy another "Yamaha" KB maybe maybe not it would depend if they learned from there "short-commings" and produced a quality product.
