I constantly hear from everyone that the SM7b needs 60dB of gain; this is even listed on Shure's official youtube channel. I disagree with this completely. If you are recording or streaming through a piece of software that allows for the addition of a limiter, such as OBS, I think you can get by with around 50dB of gain.
