[pianotech] Boston Question

[Gerald Groot]

I had a newer Yamaha U3 with a similar problem.  It tuned fine but, the
strings would creep and no way could I get it to stay in tune.  With the
help of my cousin, another Groot RPT, we worked together and lowered the
pressure on the pressure bar gently and slowly because we could see that
there was to much of an angle on the strings in that location from the
pressure bar.  The location was half of the tenor section and entire treble.
Since we did that, the piano tunes great and holds the tuning with no more
string creeping.

I've tuned a few of those and never encountered a problem.  Church
environments are tough---they might find that every piano they put in there
has the same problem.

How often is the piano moved to the recording studio?  I assume it must be
in the same building, but even if the studio was on the same floor as the
church, the jostling along the way might contribute to the problem.
