Hi Barrie, Thank you. I guess I hadn't given it much thought. I still don't like birdcage. Regards, John M.

Yes... John but it may be available from your supply houses. It is end grain felt, the grain follows the direction of the hammers - this is so the fibbers of the felt surround the string old felt get compacted and is not as efficient. Where as undemper felt just sits on the string and uses pressure to damp until it gets groves with age then the dampers part surround the string and buzz. Think of a paint brush stabbing into the strings. Barrie, -- Barrie Heaton Ý The U.K. Piano Page: http://www.a440.co.uk Ý http://www.uk-piano.org/ PGP Key on request Ý Home to the UK Piano Industry
