Martin D28's
Jimmy used at least 2 Martin D28's live. One was in standard tuning, and one was altered (TODO: Figure out which tuning and what songs, likely open G for Bron-Y-Aur Stomp/That's the Way).
One of the two Martins was marked (my unsourced notes say the primary one) with a white star sticker on the pickguard.
TODO: See if Jimmy used the Martins for studio work.
