Seymour Duncan Convertible 100. Bought it used, turned it on and it blew up a tube (literally
blew the top of the tube right off), cost me $350 in repairs... half paid for by prvs owner so
couldn't bitch too much.
Audio technica for sure. I own BOTH a Shure 57 and 58 but my AT mic is much MUCH Much better at half the price
A Pro engineer made me AB them and it was NO CONTEST! Much clearer, much more accurate rendition of a voice.
