Everyone has been a big help. Rick and Spaw;I took the factory rubber off my Shubb and replaced it with a length of flexible fuel line. This is a type of rubber(can't remember the name) which is hard but not rigid and is made to withstand gasoline.
I filed 2 shallow grooves for the 2 bass strings and it works. 100% better sound. I does not have the muted, choked sound it had before. I think I will be happy until something better comes along. Jeeply
