Customer complained that the soft pedal didn't seem to work. Found that the prop stick was not in the hole. Put it in the hole and r= egulated it. Tuned the piano. Drove away. 5 minutes later, I get a call on my cell: "Two notes don't work when I = press the soft pedal." Turn around, go back. Sure enough two notes (f3 and g3) don't work unle= ss you hit the keys quite hard. What was wrong? Hint (things that were NOT wrong): No hammer interference or any proble= ms with rubbing or interfering parts. No foreign objects. No keystick p= roblems. No loose screws. No flange problems. Nothing broken. Hint: The fix took one tool and about 30 seconds (after about 3 minutes= of professional analysis and diagnosis, i.e., chin scratching, confuse= d wonderment, and blank staring). Answer: Letoff was so early (about 1/2 inch) that, with the rest rail l= ifted, there just wan't enough oomph in the key stroke to throw the ham= mer to the strings. I ended up adjusting letoff on most notes and incre= ased aftertouch on the whole piano by replacing the front rail felts wi= th thinner ones. "Why not just remove punchings?" you may ask. (Go ahead, ask, you know = you're dying to...) The reason was that many notes had no punchings wha= tsoever under them, and many others had just one or two thin ones! I don't think it was set up well at the factory and certainly not in th= e store.
