Mike,
Congrats!!! It's great to see a good thing happening for ya! Brian, I may be wrong,(and someone please do correct me if I am!!!) but I believe "claw hammer" banjo is 5 string banjo using the fingerpicking method asssociated with Bluegrass... as opposed to the 4 string Tenor banjo which is strummed and associated more with Dixieland Jazz style.
