Hi Ron Its my understanding that this is the same stuff that Renner is using for their so called AA grade Wurzen. Tho to some degree any hammer is a result of the actual hammer manufacturing process, when pressed into the mold at the <<right>> pressure this felt is about as fine as one can get ahold of. I am familiar with how much you end up having to work with with Ronsens hammers, but the Wurzen AA Renners sold in Europe usually require just a very little needling, deep in the shoulders. The needlesare no problem to get in, and if fact if you want, for whatever reason, to deep needle right down the throat you can. I've suspected for quite some time, and especially after hearing your instrument in Rochester that medium pressed Wurzens of the sort I typically order here would work quite well with your approach and what I understand of your tonal preferences. I am quite curious about Bacons tho, since several of the folks whose opinions I respect very much (grin... but do not always see eye to eye with) speak so highly of them. If you are interested at all, I would offer to make a trade. You get me a set of Bacons for meant for a Steinway D, and I will send you a set of Renner double grade Wurzens meant for a Hamburg D. Its an open offer whenever / if ever you get the urge. Cheers RicB A few weeks back, I finished a small grand redesign and remanufacture with the low density Wurzen felt from Ronsen that Dale mentioned. I like it. It's firmer than the Bacon felt (which I also like), but not as hard as the "regular" Wurzen, which is too hard for my liking. Nice hammers! I hope Ray can get a bunch more of this felt, which fills a conspicuous gap in the hardness and density range of available hammers, for those of us looking for non-rocks to use with working soundboards.
