Wim- My preference is to diagnose until I get a real answer. A customer complained of "hissing" in her new M & H A. As I tried muted the back scale she said "It's getting better." When I muted the backscale to the top she said "Now it sounds clean." I didn't hear it as "hissing," but my ears are 30 years older than hers. Uneven hammer string contact or hard spots in the hammers could make odd sounds in the bi-chords. You can mute off one of the bi-chords and play one at a time and ask if the sound is in the single string, or if it only happens when you play both together. If it always happens on the left string, there may be a hammer allignment problem causing the hammer to strike the string with its edge. You could measure the strings and perhaps find or disprove "crushing." If you find individual odd sounding strings, you can try loosening them and turning the string. Perhaps some were turned and not others. Replacing strings "to make the customer shut up" is...well, not very good service. But there are many dealers who think that's a solution.

But even if I replace just the few that are bothering him, what happens if he still doesn't like it? I guess, to answer my own question, it's voicing time.

I’ve watched them at M&H put on a bass string, or set, then immediately listen to/critique it. If they don’t like what they hear they make more strings “on the spot” until they do like it. I was quite impressed with their “finickiness”. Bruce is a stickler for a good bass, even though he still disagrees with Del’s and Ron’s ideas of “backscale”, cantilevers and such.

When I tuned it yesterday, he complained about some tone problems in the last 7 bass notes, (G2 - B2). I was able to voice some of the problems away, but a couple of notes still bothered him. I asked that he play the piano for a while to see if the notes in question would get better with playing. The apartment in which he lives is small, and the piano sits next to an open window, which is very common here. I don't hear what he is complaining about. So perhaps it is one of perception, more than actual sound. He noticed that the winding on some of the strings are a little different than on other strings. The best way I can describe it is that the windings look like they were "crushed" ever so slightly. You can see it only when you look at the strings at an angle, with the light from the window shining on the strings. Would that cause the strings to have a different tone?
