I like to refer to dulcimer straps as "seat belts," and if I'm playing while sitting, I always buckle up.
I've been using another maker's straps, with the buckle in the middle, since I bought my first wooden mountain dulcimer, so putting the dulcimer on or taking it off requires lifting it over my head. Never occurred to me as a problem (except when wearing a big hat) - but, come to think of it, that probably hasn't looked elegant on stage.
Lo and behold, I just tried a Folkcraft strap, and it has buckles right AT BOTH ENDS. Unbuckling it is as easy as reaching for a tuning peg. This must be a godsend for players who have difficulty reaching behind their backs or raising an instrument over their heads!
One note: You may want one for each dulcimer you play frequently, because the leather endpieces are sturdy and take some finger strength to get onto your strap button. No problem - now you know what you want for your next birthday!
Folkcraft® Quick-Release 1" Wide Dulcimer/Ukulele Strap, Brown
It is the best one I have come upon for the Dulcimer I have.
I've tried plenty of straps over the years...most of which didn't 'cut the cake'. This strap, however, is definitely a keeper. It is sturdy and well made. The leather ends are especially impressive.
Sturdy strap, easy to adjust. The leather and brown color do not look out of place with dulcimer wood. Latches are strong, while easy to fasten and unfasten.
