I've not found the duplex bars themselves to be the source of noises. They certainly can contribute by how they influence the angle at the capo bar but the source of the noise is usually the capo rather than the duplex, at least in my experience. Dressing them for cosmetic reasons is fine. Also, if you like the look of bare metal, which you can get by sanding through the gold lacquer, then a rub on coating of paraffin will help with the rendering and leave the duplex protected but still metallic looking.

Dressing the duplex bars is unnecessary, in my view. I sometimes have noticed a sizzle coming from a few of them. Once the strings were off or slack and pulled to one side I would rub them superficially with some fine grit emery cloth (to remove any burrs) and then load them with graphite. Maybe overkill ... but anything which improves rendering seems like a good idea. Susan Kline OSU, Newport Arts Center -------------- next part -------------- An HTML attachment was scrubbed...
