It has arrived! Now to play it,, Low D key gives me a nice low buzz sound on low notes and is very interesting sounding on chord playing. It is different to my Meister Klasse harps and Dannecker Blues C version. The comb segments being smaller I have to pucker tighter and tongue blocking has to be more delicate or you block more than you want to. When using the deep mouth style again it is not so easy to isolate a single hole into that depression of the lower lip

Verdict so far is

It sounds good but It's going to take some getting used to
