no offense intended to cowboys or those who employ capos.
per the OP: i don't use a capo (i transpose) but it wouldn't make any difference to me what others thought if i did use one! that said: knowing how to transpose effectively is its own skill.
i'm with stringtapper and Stevorebob --- not a big deal to play that tune in those keys (or any key!).
good luck with your Db/Bbm tunes!
