4 equidistant strings/McCarty tulip dulcimer
Instruments- discuss specific features, luthiers, instrument problems & questions
Bridge - Try DAAA with the melody A string, when played at the 3rd fret, matching the bass D string but an octave higher. The A melody string will end up sharp of A at the zero fret. Now you can place your screwdriver 'nut' under just the melody string and adjust it until the open A matches the middle drones while keeping the 3rd fret 'd' an octave above the bass string. The instrument was built to be played melody against drones with only the melody string fretted to play a tune (either with a noter of a finger). Your issue is simply that the zero fret is in the wrong place.
Your DAAd tuning will exacerbate the issue of the 1st fret position. These fret patterns are supposed to have the 1st fret sounding the 6th of the scale (naturally 182 cents above the 5th). Your DAAd tuning makes the 1st fret the second of the scale (naturally 204 cents from the root note) - hence you probably have the screwdriver placed too far left. DAAd will sound OKish but you are actually not getting the best from the dulcimer as other frets further up will be thrown out.
Jim - That's a great piece of work! Very interesting how many makers ended up with JI, either because they set their frets by ear or because they copied the fret pattern from another maker who did.
