Astro: The best advice usually comes from friends who know a friend. My recommended expert in the UK would be a lad called Paul Archer, who lives in the Teeside area, North-East of England. He is a wonderful guitar player; a wonderful fiddle player and probably plays instruments I don,t know about. He builds and repairs stringed instruments.What more can you want?
