Hey all, I have (of course) an SM-57 and a 58, but have been curious about getting another mic to compliment the 57 since I use it primarily for electric guitar. I've considered the CAD Trion 7000 and the Senheiser 421 so far with having heard good reports about both. A common description is that they fatten things up, and we all love fat, right? None the less, I am not unhappy with the 57 at all, so please don't misunderstand. I'm just looking for an addition to the arsenal. Any additional suggestions that the experienced folk can throw out would be greatly appreciated. And oh, let's say sub $400-ish. Thanks.
