Partick, Allow me to interject an analogy. No matter how you shine up the hood of your car it can never eliminate the smoke from your muffler if your rigns are worn out. By this I mean that the duplex scale function is independant of other functions and is a contributing factor to piano tone. If iit is correctly tuned it will be a plus. If it is not, it will detract. Of course the strings must be seated properly in the agraffes and levelled, and the hammers filed delicately so that they all hit simultaneously. But you can file the hammers down to the moulding and never compensate for bad duplex scale bridge placement, in my opinion. Dan Franklin
