(1) Recording and studio great, Rob Paparozzi uses a SM57 and he sounds terrific! Rob's email address: chromb~arthlink.net (Rob Paparozzi). (2) >From time to time, I use a Shure Sonodyne 540. In addition to the "warm" tone that can be achieved with this Hi-Z mic (which has the vintage Shure vocal element), the diameter is larger than the SM57, and therefore, more comfortable to hold. Contact Tom Ellis at Tom's Mics (214)328-3225 and he'll be able to track one down for you. Good luck!
