Didgeridoo BF43M34B9W39P26 is Midrange didge. A very low and deep sounding didgeridoo in the tone of B. Harmonious sound and very nice for the meditative didgeridoo player. Good for voicing and clear overtones. A cleanskin didgeridoo. No knot's nothing. Very nice varnish over the red wood color. A strong didgeridoo too. I do not think it will damage quick at all when falling over or something like that. But please do not try.
