Has anyone experimented with substituting the rather thick felt strips that are attached to the spring-loaded practice pedal bar?
I find that, as intended, it makes the piano barely audible. I'd like to perhaps replace the felt strips with a material that brings the volume of the piano down...but not to the drastic extent of the fairly thick piece of stock felt. I've tried a couple things with no great success but have at least verified that different materials drastically change the volume attentuation (just as one would guess). I suspect the answer may be a slimmer piece of felt, but I'm sure there are other possibilities ...some that could be audibly very interesting and completely change the sound of the hammer attack (for example, like a tack on hammer).
There has to be something that can be used that would knock down the volume but not dull the attack as much as the standard felt strip, but I imagine it's a matter of trial and error and good fortune.
I would like to hear if any techs/players have experimented placing something other than felt in front of the hammers and have gotten good results, or if they have substituted with slimmer felts. If the right material can be found, it seems easy enough just to tear the original felt off the bar and glue the new material into place (assuming it hangs in place as the original felt does).
I'm going to post this in the tech forum as well because it's possible that techs, as well as players, have experimented and have input. Please do not remove either post so each has a chance to get responses. Thank you!
