I don't totally accept that it is wobble in the hammer during its approach to the string, nor loss of contact between knuckle and jack. I think it is wobble during contact, caused by the restorative forces of the displaced string imparting some energy back to the hammer/shank structure. I think the pinning is responsible for supplying a degree of impedance to the hammer and shank. Without this "anchoring mechanism", the shank absorbs the transient shock of contact and by its unfettered vibration, causes a short interference between the hammer and string. Perhaps the shank goes into a momentary random oscillation during contact which causes the tone to suffer, I dunno. I do know that pinning up from 1 gram to 5 makes a clear difference in tone. Ed This makes good sense to me. What does a teflon bushing do when it gets just slightly loose?
