I recently acquired 2 bentside spinets which are kits from the Hubbard workshop. Although both instruments are in good condition, the plectra & strings need to be replaced. I’ve now restrung one of the instruments using Rose wire at a1 = 440 (client really wanted this pitch). However at this pitch it’s not possible to use Rose brass throughout the instrument as the strings are very close to the breaking point. At 415 it’s possible as long if you use a rather light stringing.
Since I have the folder of this instrument, I know that Hubbard intended it to sound at 415 Hz and offered phosfor bronze to put it at 440 Hz. For the brass the folder mentions “spring brass” which I translate as “harder drawn than Rose brass”.
Out of curiosity: does someone still have the original stringing list provided by Hubbard?
I’ve looked at Stohlberg messing as well. At 415, the string tension seems a bit too low in my opinion. At 440 Hz it looks a lot better.
