Brilliant! ....for less than 10¤ I've just refreshed my Shure Beta 58 back to new condition. After years of gigging it was beginning to look old & tired, and slightly rusty blend to its colour. Bought the T-bone replacement cage and its absolutely like new again - its performance has never changed, but the appearance gives a lift to the soul of the performer. Fitting was easy without issues - unscrew one, screw on the replacement - done!! - new mic!! ...it puts the value back into your expensive mic.
