I recently got a New Bow from a UK Violin Dealer. It looked like a nice practice Bow weighing only 126 grams and is at least 75 years old. The Frog is Very low. The Bow has been appraised 2x as German and not French which was odd especially with all French Specs, Length and the Low French Frog. Well, anyway.. This Bow pulls more sound, Volume and Color of tone than my two heavier Bows of 146 and 152 Grams. I love those two Bows but this one even plays stronger and fuller sounding up at the tip (4th quarter or the stick). Is this unusual for a lighter Bow to sound thicker, fuller and more colorful than a heavier Bow also of quality Pernambuco from a good maker. It has Black hair but I am told this has a more Course pulling sound than white or off-white which I have both on my other Bows. Can the hair make that much of a difference in the tone?
