Some time ago, I was asking Maclaine Colsten http://www.youtube.com/watch?v=6WohzbfXgkg about any decent websites that help people wanting to look into buying a dulcimer.

He gave me the website for Becky Edwards AKA Dizzy Dulcimer which is a great website and well worth spending time on their.

This page will probably answer your query http://www.dizzi.co.uk/careandmaintenance.php

I hope that helps.
