1 tenor + 1 bass = A; 1 baritone = D

So, there is another post on this blog regarding an E baritone drone (here), but here you’ll find a D baritone drone. This is obtained with the same setup as before (bass drone bottom, tenor top for the middle drone position) but with a Wygent double tongued bass reed plugged in to a Dunbar tenor drone reed seat extender plugged in to a Dunbar bass drone reed seat extender. :o) Otherwise, 1950’s Henderson pipes with Selibe tenor and bass reeds. Delrin Apps Chanter with Apps G3 reed. Check it out:
