Kawai KG-2C vs KG-2D difference #2477383

I guess back in the mid 80's or thereabouts, Kawai came out with the KG-2D which I read was an "improved action" over the 2C. Can anyone comment about what the change was? I'm looking at buying a 1985 KG-2C and I think the price is a little high so I'm wondering if it's worth holding out for a D model. This C model however has had very light use...barely any visible hammer wear. I have not played the D. Only the C and the E and I thought the E was way too bright.

Any thoughts from the tech side of things? Very few used grands in my part of the country.

Hello, I only can talk of how the first Kaway KG2C came here

THe importer did not like the hammers and they where all replaced with very heavy Renner hammers, obtaining indeed a muddy tone but a power sensation that was may be the goal (Gr 6 hammers where usually that size is only for large grands , thick felt much compressed G3 5 or 4 is find in smaller grands)

"play like truck" is the most common comment heard

(may be the hammer change was done at the factory for the French importer, I justr dont know)

That said I had to work on some of them 30 years later, and the very thick hammers did leave much felt to reshape

It wads also possible to lighten up somewhat the touch (originally about 80 g and more in basses)

I remind also that the whippen, rail was not secured, just holding with screws (no shims) so at some point if those screws where not secured from time to time, the whippen rail did move toward the keyboard and made an implacable action till repaired.

The Renner hammers are easy to recognize, red underfelt very thick, felt a little yellow. brown wooden core.
"ref numbers written on one of the first hammers on the long bridge at the break, stamp Renner in some of the first basses, while as there are some extra hammers in a set the stamped ones are not always retained.

HOpe it helps

80 piano barely played can be a good choice

Just check the strings grooves with a nail, not just visually threw the strings, as they always look better than they are .

Send some pics of the hammers I will tell you if they are Renner.
Those pianos where proposed to school at an era where the trend was to have a "heavy" keyboard (many brands did confirm to that inquiry and modified a little the action setup to obtain that)
Sometime it is possible to backup a little, but an action implementation optimal leaves not a so large margin when it is a little edgy.
When lightening by changing some action setup distances, friction can rise and make the result less enjoyable than expected. (the height of the stack need to be modified, which is not so easy to measure and realise)

Thanks very much Olek. I'll take a look at the hammers. If there was a problem on the early C's maybe it was corrected by 1985.
