Hi Gordon.. Sounds to me like you have pretty well established that the dead thudish sound has nothing to do with the strike line... yes ? That means something else in in the way. You could always try changeing a few strings and the like.. but I doubt that will make a lot of difference. You may just have a piano thats dead up there. No sustain points in the direction of a bridge/soundboard that simply sucks up all the strings energy and reflects none of it back. Could be a host of reasons for that being the case..... One question... is the transition from Eb7 to E7 and above abrubt... or is is a bit smoothed ?
