Frank set up my "old" RB250.......there is a gentleman down near Glasgow that does the best job in the world on set up......the neck on my Mastertone wasn't fit properly at the factory..........his name is Arther Hatfield.....he has a page.......Hatfield Banjos....he messed with mine for three hours or so............He charged me a whopping $50 including a new set of strings.........he had it sounding sweet for sure.......if my finger heals up.......I need to take my banjo back and get it tightened up.....otherwise it will sit in it's case......
