Audio-Technica ATM650 hypercardioid dynamic microphone to replace my Shure SM57. The ATM650 has a slightly more aggressive midrange and less high-end fizz than the SM57, whilst retaining all the best qualities such as a weighty low-end response, superior isolation and tough-as-nails workhorse build. I shall henceforth be using it to mic up my guitar cab for future riff videos, so prepare thy ears for some serious crunch!
