Conversely, trying to lower the pitch even with hard blows >takes an unusual amount of effort... >Roy Ulrich Some additional info, maybe relevant for your situation, maybe not: Perhaps you missed this information on an early post, Roy. Tuning can be tricky, but not because of pinblock tightness [or the pressure bar], but rather too close tolerances in some of the tuning pin areas, making it difficult to render the strings. The tuning pins are not necessarily spaced accurately in the pinblock causing the strings to rub against their neighbor strings. The strings are bunched up against one another. So when you have finished putting one string in tune and go to the adjust the next tuning pin, the string disturbs the one you have just finished. And vice versa.
