Got a DeArmond Rhythm Chief 1100 for my archtop. I tried to get a beat-up one that was at least duller, but what arrived is shiny-bright gold, which really doesn't match this guitar. I'm thinking a dremel with a wire brush might be the ticket, but this place is always full of good advice. Any tricks to turn this gold to silver? If the recessed parts remain gold, that's cool. Just hoping to get the main casing.
