Question for those who have great experience with WNG action.
I had WNG whippens, shanks, and flanges with Ronsen Weickert hammers installed on my S&S model B, and I love it!! I can't say enough good things about it. The original install was in October 2017. My technician said let's let it settle in a while and we did. He came back in November 2018 (a year later), about 3 months ago, and did adjustments and voicing. His 1st comment was that the aftertouch was gone. He commented that it must feel like playing on bricks. Of course, playing it every day, I hadn't noticed too much as it is with gradual changes. He said it had really settled. So he made all the adjustments, and it made a huge difference.
Now I'm wondering if it has settled again 3 months out from that last adjustment and if this is normal. I have played it quite a bit! I haven't done any actual measurements, but it seems I don't feel the aftertouch when pressing on the keys slowly. Could it be that it feels more "settled" b/c it's to cooler, drier season which has compressed the felt parts in the action? I know WNG CF actions aren't supposed to be affected by climate changes. Maybe the drier air has affect the hammers enough to make a difference. I'm keeping RH between 35 - 40% right now with a humidifier. It runs 45-50% in the summer months with a dehumidifier.
He made the adjustments around the time the weather broke into the colder, drier pattern here in Indiana. I plan on having him check it out when I have him come back to tune again. I'm trying to wait until April or so, but I'm wondering if I should call him back to check it out now or just wait until my normal 6 month tuning.
Your thoughts. Thanks for the advice. Maybe others will learn a little something here too.
