I know this is not the best forum in which to ask this question, but I figured someone on here might just know the answer. So it never hurts to ask, at worst I'll ask somewhere else. Ah, the acoustics engineer who mixes for the Tannihill weavers used to be on this list.. Too bad he got really busy and signed off.. A friend of mine advised me that he solved some problems he was having with feedback being generated by a particular type of hollowbody guitar, when amplified to even just moderate volume levels. I was particularly interested in his fix, because I was considering buying one of that particular model. The body of this hollowbody guitar is kind of like a fiddle, with a carved top, f-holes and an empty inside cavity. What he basically did was measure and cut a wooden dowel, then experiment by moving it around on the inside of the body, till he found a spot underneath the bridge that seemed to kill most of the feedback. Here's a copy of his question:
"I been thinking about soundposts and fiddles... Here's why I figured fiddles got 'em: Without one, the strings/bridge just vibrate the TOP; with one, the bridge can vibrate the TOP and the BACK together, - making it louder. How come it keeps an archtop from feeding back then? It prevents the top from vibrating on its own - with a soundpost, ya gotta move the top and the back to get it going... Well, that's a bit weak, but the best I could do." Is this the real reason that the feedback he's onto, or is he way off-base. Thanks!
