Howdy First the good...now the bad! I'll start it off... - All the horrid FM ripoffs Yamaha made. There was one in particular that was the most gawdawful POS that I've purged the model number from my mind. It was a Y - something or other. More of a home keyboard with a gigantic volume knob on the left side. It also had these "channels" imbedded into the front panel linking various functions. If you stood it on end, it resembled a "stick man" doing a "jumping jack"...horrid! Respect to my Yamaha homies but man...that thing was subpar.
