Recently purchased unknown Pernambuco French bow that looks and has similar specs to the Pernambuco Double Bass Bow at Gollihur Music - Double Bass, Upright Bass, String Bass Specialists Previous owner didn’t use much and neither did I. Some Kolstein rosin on it. Comes with pictured sheath. My teacher thought it was a very good quality, esp for a first bow. That said, he agreed that I sounded and looked more natural when I tried his German bow. Looking for a comparable German bow in trade. If you have something let me know. Thanks.
