I've owned several A R Kern instruments over the past 3 or 4 years.
They have all been pretty simple, with four tuners all on the left side of the head, hourglass in shape, and the were generally all of one wood, whether cherry, walnut, or something else...that is, the top sides and back were all from the same wood.
I was impressed with the sound of each one, some brighter than the others, depending on the woods, I suppose. All had good volume. The sound holes varied, from instrument to instrument. The workmanship was very good.
I have paid as much as $200 for one, but they are more prone to sell in the $125 to $150 range lately, depending on the woods used, and the condition of the instrument.
After A.R. passed away, his son built dulcimers for awhile. I don't know if he is still building or not. I may have his business card at home, if you would be interested in contacting him. If I locate it, I
will send the information to you.
