We have an old, iron-framed honky tonk American piano (nearly 100 years old approx).
Nine kids learnt to play on it, so it has enormous sentimental value in the family. We've spent literally thousands on it over the years having it tuned and restored, felts replaced, hammer repair from swelling caused by humidity ect... it's never just a matter of 'tuning'.
But the reality is - it'll never play as intended back in the early 1920's. They just don't last. You can restore and tune them all you like. That being said - I love how it sounds - warts n' all. It has character. I love the quirky off beat (tune?) sound it has - and have gotten used to that pesky D Flat sticking when it feels like it... I just play around it
I'd never throw out an old piano with family history. Never.
But yeh... I also have a digital now, lol, and love it for a whole different set of reasons
