I just got my Shure KSM 137 small diaphragm condenser mic. I bought it to record Cymbals/Hi-Hat, brass, woodwinds, strings and other acoustic instruments. The manual however however says that you can use it on guitar and bass amps as well. I actually never thought of using small diaphragm condensers on amps. Does anybody here have experience with what I mentioned above? Be it bass or guitar amps, be it the KSM 137 or any other small diaphragm condenser mic.
