My instructor there, at the time, showed me the difference between the=20= smaller side of the punching up, and the smaller side of the punching=20 down. It did clearly make a difference in sound. One thing I have learned about this new Wurzen punching, is, that if an=20= instrument has not been regulated the right way, or when an instrument=20= has very loud hammers, you will not hear any difference. You will hear a difference though when the instrument has been=20 regulated the right way, and when the hammers have a more or less=20 'normal' voicing, i.e. not really too loud, and not really too soft. There is of course a wide scale between very soft and very loud, but=20 then..... those two are extremes. The influence of the new tapered Wurzen punching is subtle, and can=20 only be heard on an instrument which has been regulated and voiced=20 according to 'normal' professional standards. The feel/touch of the new punching on the other hand, is an other case=20= : 'any' regulation becomes more clear and more defined when you install=20= these punchings. How can it not be the case? It is a more dense material with a very satisfying elasticity which=20 Vladan Temer described so clearly before when he tested several kinds=20 of punchings. That means that a key dip of 10 mm is a key dip of 10 mm. No more, and no less. That in itself makes all the difference. Capisce?
