Good evening everyone! I had written as a follow-up to an existing post, but perhaps it is more appropriate to create a new one... I should mention that I have a family Yamaha G3, a '72 all-original, and an '84 C5 in my studio, imported from Japan which I purchased recently. On the G3, perhaps after 50 years, the hammer felt should be replaced… what do you recommend? Abel natural (medium or hard?) or is there a way to source original Yamaha hammers?

The '84 C5 that I have in my studio has a hammer felt that looks new; however, the inscription "Yamaha c3.5" on the first hammer to the left suggests it might be original… is it? Is there a way to tell if it is recent? The sound of the C5 tends towards warm; the instrument is not "screaming" like the G3 I own… out of further curiosity, would mounting Abel natural, Wurzen felt, or Yamaha hammers from the more recent CX series on the C5 potentially be an upgrade worth considering? Not that there is a real need… I am asking for the sake of knowledge.

I still need to consult with my trusted technician, but in the meantime, I wanted to test the waters and understand what can be recommended and what should instead be avoided. The idea of customizing the sound of one's own instrument is very fascinating… even if, on the other hand, these are potentially not painless experiments...

Thank you for your attention!

I would install an ABEL for Yamaha on a C5, but not in natural felt. It is definitely an upgrade. The designation c3.5 should indicate a different hammer size and a different drilling pattern. But the technician will take care of that. Avoid shaving the hammer heads. This changes the striking point and also the geometry of the entire action.

I wouldn't advise against it. I find that it is less close to the one installed by Yamaha. Besides, you can't say for sure "in the dark." One would need to see the old one and also the desired sound tastes.
