There are some pianos--not many, but some--that I've learned are best left
alone. They really are sow's ears and they ain't never going to be even
naugahyde wallets, let alone silk purses. 

You can make these things a little less bad but, try as you might, you're
never going to make them more good.

<What is the reason for the extreme nasal and weak tone of the upper bass? I
can see that the upper bass backscale is quite short. There is about a
one-inch-wide cantilever on the bass bridge. But what on earth accounts for
SUCH a horrible crossover? Is the upper bass too close to the rim? Wow.

Sounds like all of the above.  The entire bass bridge hugging the rim is 
a real challenge.   I've tried, with limited success to overcome that 
close proximity by floating the entire bass bridge,plus vertcal hitches, but
it really didn't do the trick.  The nasal quality remained.  It does'nt have
to be as bad as the present victim's tonal condition, but I'd love to hear
ideas on whether its possible to really get past that soundboard
restriction.

How about taking a cutting torch to the plate and moving the bass bridge up
4 inches, or even better, putting the miserable thing out in the backyard
and planting strawberries in it...poor thing?
