ETD's accurate?

[Alan R. Barnard]

I use the box but I TRUST my ears. In other worlds, I use both.
Specifically, I check/adjust at the breaks and when the string type (or
number per note) changes. Also, I only tune wound strings by ear.

It seems the ear is still more "accurate" when it comes to any particular
piano--and especially quirky or poorly scaled pianos, tired old strings,
etc.

But those who haven't succumbed to purchasing an ETD do not know the joys of
truly fast and accurate pitch corrections, methinks, and the help they can
be for fatigued ears--especially in the high treble. Also for diagnosing or
demonstrating string problems to the client, etc.

Strangely, ETDs are also wonderful for teaching to tune by ear. At least, it
has been for me.
