I am a professional piano technician (more about that here), who is new to the player piano game, and to the blogosphere, for that matter!
I reside in the sleepy realm of County Lunenburg, Nova Scotia; arcadian from June to September, and rather boreal for the other two-thirds of the year.
Note: I see that the most common questions and comments are specifically regarding Willis brand pianos. Please have a look at that post here, and read through the entire post and comments first.
If you still have a question, please comment there, thanks!
