Hi all, I've been a pro Dulcimer player for many years and have found that there are two good ways of ampflication, first is a sterio pair of condencer mikes (cm1000s are ok). Second and more interestingly, go to an electronics store ie: maplins and buy a piezo crystal disc(two brass discs with a piezo crystal filling) They cost about 50 pence, try to get one with a peel off sticky back. Attach to your dulcimers soundboard (experiment before you stick it down for the best position). Solder a wire to each of the discs and connect a female jack plug. That's it, your ready to go, no pre-amp needed (loads of signal) no feed back.
