List, My main problem with Y-C grands is that the jack slips out from under the knuckle on harder blows and the note will not fire and must be re-positioned on many of the notes, also true on the Wurlitzer Y-C's. There is very little clearance to get the tool thru the dowels in front of the regulating screws. James Grebe from St. Louis pianoman@inlink.com
