The intensity of the opening to a piano regulation video... amazing.

As a new piano tech in the field, this is exactly what I was looking for. Thank you for the clear visuals and instructions!

Thank you so much for putting this together, many technicians act like piano regulation is some sort of black magic.

Thank you so much for this video!! Regulating is the worst part of restoring pianos for me and I'm so grateful for this simple explanation of the regulating process!!

With the high cost of paying someone for piano regulation, I'm only using this to help me start regulating my own piano. I bought it for cheaper, and knew it wouldn't be perfect, so here I am haha.

The very best explanation of the grand piano action to be found on the web

[jenl]

This is a perfect example of how all should be done & truly appreciate it. Wonderful to see it explained so well as you do & so helpful.

This video is a huge gift! Thank you for showing this process! This helps me to understand the grand regulation processes that I am reading about in resource books and is hugely helpful for someone like me who is studying to be a piano technician!

Very helpful overview. I'm a newer technician, and have taken a more extensive action regulating class, which was great but a little overwhelming. Your concise instruction demystified much of the complexity of the process for me.

My goodness thank you for dedicating your time to teach how to regulate a grand piano. Beutiful explanation. God be with you. Again thank you.

[colesnapp]

This is the only video I have found that went through the whole sequence. I understand it so much better now. Thank you!

Thank you for this video, Michael. I love the PTG's 37 Steps of Grand Regulation. However, you totally simplified it. Thank you. I like your idea about setting drop before letoff. You covered 30 pages in about three minutes. Simplicity is genius. Much appreciated! 👍

Very cool. As the proud new owner of a baby Grand, I was a bit overwhelmed by the choices on YouTube. After watching the first half of many, I found this one. Great combination of using "feel" as well as measurements.
Nicely done.

Thank you so much for this video!! After watching this, I realize that the piano tech I hired did not do a good job. The action was clunky and difficult to play softly. After I, a beginner, regulated a full octave by myself with what I learned here, it played like a dream!

Thank you - I have never seen a video this good for regulating a grand action. This makes the procedure much easier to understand.

This is a good video! A lot of comments seems to come from people who has a good bit of experience.
This action is in good shape already regulated.
There is quite a bit of work to get it that point. Unless it’s in good shape regulation wise when you start.
Asian piano actions don’t change much from piano to bench.
On American piano actions some change from piano to bench meaning redoing some reg. Points.
Some techs bed the action when in the piano. Along with other measurements.
You can take the stack off. Put weights on the keys. Put key frame back in. For dip. setting key height samples etc.
while the frame is on bench clean the bed lube key pins. Check for key checking when taking keys off. Making sure keys are free.
In the beginning do all repairs first.

Thank you. Very clear - no waffle! Also the “why” and not just the “how” help me adapt to my 100+ year old piano. 5*

[ivell]

Thank you so, so much. I´m just regulating my grand myself now, like I really wished for a long time. Extremely valuable video.

[roy]

Awesome. I know it but sometimes as it’s not my main task and I mostly tune, it’s good to be reminded with a solid system of checks. Thank you.

[fiokomjutub]
