[CAUT] Imperial with breaking bass strings

David and all,

IC has a 1953 Imp Bose that has suffered from regular string breakage in 
the past. The breaking generally happened in the bass and treble. This 
piano lived at Cornell from about 1974 to 1989. The technician at 
Cornell informed me of this problem and suggested regular string 
replacement in the treble every five years or so to keep down the 
inconvenience of having to replace just before, or during, a concert. 
For the bass, he had replacements handy when needed.

The first winter here at IC was very telling for this instrument. It did 
not like the low humidity in the building and let us know. (It suffered 
similarly at Cornell each winter as well) Someone would be playing and 
suddenly there would be a loud cracking sound. Most disconcerting! It 
took a bit of searching to discover what was happening. The noise turned 
out to be the veneer splitting on the inside of the outer rim. This was 
obviously due to the dryness.

Also during this first winter we had a number of broken strings to 
contend with. By the end of the winter I had installed a humidity 
control system on this piano. Since then I have had little string 
breakage and no more loud cracking sounds. There is something to be said 
for proper humidity control. :-) This may not be your problem but the 
fix worked in this instance.

>Hi all: anyone have experience with a twenty year old Bosendorfer Imperial? I saw one yesterday that had several bass strings replaced previously, and one broken when I arrived. while tuning two more broke at the becket. Just wondering if anyone else has seen this problem before. BTW, none of the broken/replaced strings are in the extended range of the bass. Thanks
