<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Come to think of it, it is entirely possible that some Z kit instruments were designed for 415, without transposing keyboards, in a sort of quirky authenticity phase. Ed Sutton's right, call Zuckermann. But have some specifics so you can describe the instrument. Length, range (eg B1 to D6) in particular, history (age) if known, whatever else you can gather.<DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>If it _was_ designed for 415, it is possible to make it play 440 by turning the keyboard into transposing, which involves removing the top key and cutting the keyframe, and some other adaptations. Or that it could be altered simply by changing to modern wire rather than low tensile. <BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV>Regards,</DIV><DIV>Fred Sturm</DIV><DIV>University of New Mexico</DIV><DIV><A href="mailto:fssturm@unm.edu">fssturm@unm.edu</A></DIV><DIV><BR class="khtml-block-placeholder"></DIV><BR class="Apple-interchange-newline"></SPAN></SPAN> </DIV><BR><DIV><DIV>On Sep 21, 2007, at 2:12 PM, Fred Sturm wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite">Hi Bob,<DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>I happen to be placing an order to Hubbard just now, and looking in their catalogue, they say that 13.5" is the maximum length for c" (which I think translates to C5) in low tensile wire, 16" for high tensile, both at 440.

Which is an execution problem, not a design problem. Depending on era, a Zuckermann is quite likely to have low tensile strings on becket-less tuning pins. In changing a string (or stringing), to avoid the described problem, bend up or break off the last bit of the end of the string before you get to the final coil around the pin, so the coils aren't crossing it any more.</DIV><DIV><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>I guess I'd be surprised if even a very green kit builder put a bridge on far enough from where the plan template wanted it to cause this problem.

I don't know if this was a kit or not, but the coils on the pins are not very neat, so I suspect it's a kit. When I tune it to A-440, strings break. I've currently tuned it to A-415 (one semi-tone flat), but the music director isn't happy transposing everything.
