Blatent commercial endorsement

[Andrew and Rebeca Anderson]

Ron,
I have a 490ST gathering dust in the bottom of my closet.  The 
problem with the 490ST is that it doesn't calculate stretch to fit 
the little beast in front of you.  You have to do that on the fly 
and, that little touchpad doesn't touch fast enough to add or 
subtract cents.  If they had made it a turn knob I probably would 
still be using it--not if I'd tried a VT100.  The 490ST does not 
differentiate very well at the extreme ends of the scale in the nasty 
little pianos.
The 490ST gives you interference patterns to work with.  They are 
stretched by templates that don't accurately fit most pianos you 
encounter.  If you look in the back of the manual you will see the 
stretch tables they utilize.  You will notice they are quite smooth, 
calculated.  Sit down in front of that Betsy Ross and check out the 
break to the bass bridge.  If you want to make that sound good it 
will not be a smooth curve.

For fine concert tuning work you need to consider all the breaks in 
the scale.  Every change in wire size, and/or in wrap size is a 
scaling break.  A fine tuned concert grand will have all those 
scaling breaks neatly tuned and unobtrusive to the tuner's ear.  If 
you are relying on the 490ST and not checking intervals and adjusting 
as you go, you will not have the best possible tuning.  Compared to 
older style tuners that rely on a FAC to calculate a curve it is 
stone-age-ware.  Compared to the new tuners that calculate each note 
by its inharmonicity as you go it is: well, kind superlatives aren't 
existent. ;-)
