Works great for everything from drums to guitar amps to acoustic guitars to vocals and really just anything you need a no frills stick a mic on it recording. Incredibly durable, has been clipped quite a few times with drum sticks. Stock clip fits well. It’s often cheaper than an SM57 and works just the same.

El mejor micrófono que he usado en el servicio de la Santa Misa. Sonido súper balanceado entre bajos, medios y altos.

Il rapporto al denaro speso per l'acquisto del prodotto, in cambio (oltre alla nota celebrità storica del prodotto che parla da solo (era la tipologia di microfono utilizzata dalla voce di Freddie Mercury!), la sensibilità del dispositivo, la sua capacità di esaltare la voce, i toni, la timbrica, sono incredibili.La robustezza inoltre è eccezionale, basta toccarlo, sollevarlo e tenerlo in mano per apprezzare la solidità del microfono e anche se, ovviamente, non ho eseguito alcun "Crash test", la sensazione che ho, confermata dalla diretta esperienza di alcuni musicisti, è che resista ad eventuali cadute (in alcuni casi sono state riportate cadute rovinose), senza conseguenza. In altre parole e in particolare per le mie esigenze non avrei potuto trovare di meglio.

The sound really impressed me a lot, I DJ and I have a very deep voice. This mic is one of the 1st that made every word just sound so smooth. No distortion or feed back, made me want to talk a little too much at times lol. Truly worth the money.

This is a Shure mic, it looks incredible, it's heavy and robust. The sound is bright, lots of colouration towards the high end, not too everyone's taste, but brings out a dimension in the performance that is hard to ignore. If you're looking for the instrument version, the 545SD has you covered.

I was leading worship at a friend's church, and half way through rehearsal, he said, "Hold on, I want to swap out your mic for a different one". The mic he brought out was this one. At first, I was like, "Is that from a cheap karaoke machine?", but then he told me that this mic was allegedly Freddie Mercury's favorite mic, and it has a great clarity. I decided to give it a shot, and I was completely surprised. First, I hadn't even heard of the model, and second, that it sounded so good! The mic it replaced way probably $400 - $500, and it was awful, by comparison. After church, I went home and ordered this mic, and have subsequently used it at my church, once, already. I was leading a song with my wife, where I had to do delicate falsetto harmonies, and I felt like I had all the clarity and response I needed in order to relax and just sing. it was great.

This is a beautiful piece of gear. I mostly bought this microphone as a back up vocal mic. The reason i chose this mic is that it is seen in many old classic music videos and pictures of various artists. Brian Wilson used a unidyne mic along side a U47 for lead vocals in the studio. Its the only piece of equipment that i purchased mostly on the basis of visual appeal. The only reason a withheld a star is, it does pop (plosives) a bit without a pop filter. This is a cheap easy fix. It sounds excellent on vocals. There is nothing cheap sounding about this mic . It allows close singing for proximity effect and very smooth highs. If you want to use this as a vocal mic, get a pop filter.

This microphone is fun for Freddy Mercury fans who want to use the mic he was known for using while live. I have been on stage many times with a Shure SM58 and was served well by it, but I wanted a mic with a little less bass while using the proximity effect, and this seems like it did that for me. It is the predecessor to the SM58 and both looks and sounds sort of like it. I wanted this microphone for its very distinctive sound profile and was happy with it. It seems very durable, the switch is well designed and is totally silent in many circumstances, but can be locked into the "on" position. My m-Audio Fast Track Pro digital audio interface was not working well with this mic due to low output causing me to have to raise the gain to a level that caused a lot of background noise. I solved the problem to my satisfaction with a Cloudlifter Mic Activator, which is a preamp that is phantom powered and small enough to tape to a mic stand. I could then lower the gain on the audio interface to get a cleaner sound. After this setup was achieved, I was totally happy with this microphone.
