ETD comparison

[Clyde Hollinger]

Friends,

I have an idea for a chapter technical, or maybe even at a convention.
Has anyone tuned a piano with 2-4 ETDs (electronic tuning devices) all
running at the same time?  It would be interesting to me to know how
much they differ from each other and where and why.  I'd like to try
this in our own chapter sometime, comparing SAT, RCT and Verituner, all
of which are represented in our chapter membership.

Regards,
Clyde Hollinger
