Hello, Robert. Thanks for information and the microphones you've suggested! I'd like to have both good GBF and rejection and sound quality. In past gigs, I usually do not hear myself enough in the monitors with the SM58. In rehearsals, it usually does fine without much tweaking at the PA console (nothing fancy) but I kind of just feel that the tone can be better. There seems to be too much coloration and I just don't sound like me. At times, my bandmates thought I sounded like I'm in a can or that I sing into an amp and then mike the amp up. There is certainly use for that kind of sound but most of the time, I prefer to just sound pretty much like me.
