Yes, it seems that the hammer felt absorbs left-over finger oil and grime. After a while the tip of my device leaves little fly specs of grime on the keys. Then I file the felt a little. Needless to say, my hammer gets quite flat after a while. I wish I could find something that wouldn't get grimy yet was soft enough to protect the keytops. BTW, I have added a momentary switch to my device to switch notes on my SAT. Works great - no kicking a footswitch around or reaching for a tuning lever switch. Mark Story.

Like I mentioned previously, I use a bass hammer on the end of my brass rod, and have to change it for both reasons mentioned above. Doug Mahard
