I have used these Folkcraft machine heads over several years on dulcimers I have built and on one I modified with a four set with good results. I have some a set this moment ready to install on a dulcimer I working on. I've had no problems and would recomend them.
They worked great on a recent dulcimer build.
Good parts. Tuners work well. All RR&J friendly. BTW, ever hear of “Original Mountain Music Dulcimer” Paradise, CA?
Good quality at a good price. Fast delivery
