These mics are great for the price, but the minute I rack mounted them, they became very 'hissy'. I know that cramming them in a rack with amps, etc, isnt the best thing for signal, but I need them there and unfortunately they couldnt quite provide the sound. Out of the rack though, they sound great! Just remember that they are analogue so interference can be an issue. If you're not playing large venues or just need a mic for speeches, etc, these would be more than adequate.
