Black Cat-- I did not turn the felts around-- they were fine. I did add a few chords in place of other unused ones-- that depends on what keys you want to play in. I'd suggest you ask a good instrument shop to help you unstick that C chord-- there can be several causes and it would be far simpler to let the pro's show you how to maintain (or how they fixed) your 'harp than to create wads of text here that might not apply to your situation.

BWL-- Seen them, I think they're kinda clunky too. I like mine being out of the box-- better tone.
