I use one mike stand that holds two micc. At the top is a flexible goose neck that can be bent down when playing the fiddle. Quite by accident I discovered that if you leave one of these flexible goose necks out in the rain for a few days the insides will rust and tend to stiffen. This makes them a lot easier to adjust and they loose their tendency to droop. The bottom mic has an addaptor the screws on to the vertical portion of the stand.
