Voicing of high bass on Steinway L

[Bec and John Silva]

Hello,

I know the Steinway L's high bass section is notorious for being  
problematic, but I am looking for advice from someone who has had  
success in getting an excellent transition from the B to the Bb -  
i.e. retaining the "buzz" from the C28 and B27 through to the Bb26  
and A25 while maintaining a decent tone and moderate attack.

I almost gave up hope of getting the sound, but just today I heard an  
old Steinway L that had the *exact* the tone I was looking for: the  
highest notes matched the low tenor extremely well, I was very  
surprised just how well. A full tone with some (good) buzz. I'm  
fairly certain they were original strings.

So, I'm assuming there must be someone out there who knows what I'm  
talking about and has some advice for voicing the hammer to get this  
tone (as best as is possible, at least). For those who are familiar  
with that not-so-pleasant sound that is so often in that Bb26 on L's  
and sometimes the A25, I figured they may know a general approach to  
relieving this sound.

Thanks!
