It is not at all unusual for bass hammers to lose a lot of power and focus from mating issues, and bichords are often quite badly out of level (not to mention that if the hammers are hung at an angle intentionally, that will cause a mating issue). Also, bass sections tend to be the worst for having travel that all goes in some direction, and hammer angles that are likewise all slanted (and not necessarily the right way, or too much the right way). Among other things, this leads to a bit of brushing of hammers (maybe just the loose fibers, and you can't see it) with their neighbors. All these little things together can add up to a lot of mush and lack of power and focus. Regards, Fred Sturm fssturm at unm.edu "I am only interested in music that is better than it can be played."
