Sorry, that was tacky as hell of me.BOB GIBSON, on his early records, strummed more than anything else and he avoided the thumb string back then but had fine effect anyhow while performing. Later on he incorporated the fifth string more in rolls and arpeggios. But that was by choice. Have you lost a thumb? If so, all the best to you. Please pardon my well-known insensitivity just to spring a pun again, and again, and again...
