This
is not a comprehensive list, but should give you an idea what I do
when I regulate.
There is also the option of just improving one area, kind of a
band-aide approach. From my experience, when I do a complete
regulation, there is a considerable amount of time in prep work, repairs and
reconditioning. This lays the foundation for a successful full
regulation, this is why it can take 15 - 20+ hours. My process is
complete and exhaustive.
*Once I have had a chance to evaluate your piano, I will give you
a quote to consider. Typically deeply discounted. So even if it takes 10 or 20+ hours, your price
will be known.
As
a pianist, this will give you:
Absolute Evenness
Perfect Alignment
Predictability
Control
Power
Dynamic Range
Speed of Repetition
Overall, making your
piano a joy to play. It will likely be better than when the piano
was brand new. The procedures, methods and tools I employ have
improved immensely over the last few years.
