Just curious, in what way would you "soup" up a Bluthner?
Hi Kamike, (to the Fiddler on the Roof Tune of if I were a rich man)
If a Bluthner Model I I had and all the money to make it sound my way
I would add little specs of bronze to the hammers, springs to the action, and Stanwoodize the action; the feel of the action would be on the light side, but not too light.
I would add a side post and reinforce the back posts;
I would get the soundboard voiced, by replacing the original ribs with I-ribs, placing bronze masses in strategic spots in the soundboard and filing the edges of the bridges to get very precise and stable termination points for the strings;
I would have the pins in the soprano register relocated, to have longer strings in the high treble;
I would have the key covers replaced with legal mammoth ivory;
then I would have Sam Powell voice it to my taste quite regularly (perhaps as many as 6 times the first year).
And for kicks I would have it decorated in the spirit of a Flemish harpsichord, pastel colors and floral desings and probably a Watteau-like scene under the lid included, just because I think Black or Rosewood are too severe for the Mercurial tone I expect I would obtain from my souped-up Bluthner.
It is just a dream, though. I would need to have taken care of many a more practical expense before spending the 100K plus that such intrument would likely cost. If I could get it for 35K, I would buy it tomorrow.
