D. Chitwood: Ok, Dusty, I'm going to play the ignorant person here. Are you saying get a microphone stand, like what Elvis sang into (I'm showing my age and my first crush :) ) and put a mic on it called the Sure M57 and I'm assuming you place this right up close to the dulcimer?? And the Mic attaches to the amp? If you can draw a cartoon, that would be even better. :) :)
Basically, you got it, Dana. I can't draw so be glad that I am not trying.
Here is a pic of me playing my Ron Ewing baritone dulcimette at the faculty concert of the Berkeley Dulcimer Gathering. There are two mics in use, one by my left foot for vocals and one by my right foot pointed directly at my dulcimer. (And notice that it doesn't have to get that close.) I switched between two dulcimers that day, and you can see that I wouldn't have to make any adjustments to the mics (although the sound guy did have some work to do in terms of equalization, I'm sure).
That day the mics probably went directly into the PA system, but when I plug in by myself, they go into my little Fishman Amp. I'm sure there are lots of mics out there, but the Shure SM 57 is the workhorse instrument mic that is ubiquitous in studios everywhere, and the Shure SM 58 is the same but for vocals.
