You can hear the differences among these weights in these three sound files. They were recorded seconds apart on the same banjo (A Ramsey Fairbanks Electric), played as closely alike as I am humanly capable of doing, i.e., the only thing I tried to change was the bridge:
Please remember that tonal comparisons of these three thickness are only valid on this particular banjo--different tone rings, etc., will greatly affect the tonal differences!
In October, 2003, I received a Lee Ovilla with a Tony Pass "Lost Timbre"12-inch pot with a wooden tone rim; I
recorded the instrument with its stock bridge, and the next morning, I installed the purchaser's requested Moon brand 5/8 heavy bridge, and recorded it again, playing the same tune (Lost Indian), but a little faster (hey, I'd had a good night's sleep). I think anyone can hear how
the Moon brand fills out all the tones, giving real body and substance to the highs as well as the abundant lows of this powerful pot!
To purchase Randy Stockwell Moon brand bridges, I recommend Elderly Instruments.
