Dearest Liszt: New client with 6 mo old M&H model A, today was his 2nd tuning. Very clear 3 to 5 second resonance evident at G2-A2 a couple of notes below the break. Resonated 3 octaves higher. Imagine an old-fashioned metal orange juice can vibrating quickly. Couldn't voice it out. Present on all 6 strings. Not in the duplex or front scale. No loose screws in the action or cavity. No change in bzzz volume when I applied hand pressure to long and bass bridges or the ribs or soundboard immediately below. Appears to be localized at or below the plate where the last wrapped strings cross plain wire, down by the long bridge. Irritation is even more prominent under the piano. Another client with an older A has similar symptoms. He has never been available to help me chase down the bzzz. I'm guessing that this is more design-related than string related. If this is a gift of the longitudinal mode, then swapping stock strings will probably have no impact. Anybody else experience this problem? Ideas? thanks Terry --------------------------------- Don't be flakey. Get Yahoo!
