Charter Oak SA538 by mahasandi
I do not own this mic but have worked with it.
It is a good vocal mic. Of course it depends on the voice but on one female artist this mic out performed a Telefunken M16II and a Brauner Valvet.
It has a really lush character but maintains presence in a mix.
If you’re a small studio that wants to buy a nice vocal tube mic, but can’t afford both a C-12-ish mic and a U 47-ish mic, you simply have to audition the SA538. While it’s not a direct replacement for either, it’s a solid performer. Likewise, for location or mobile gigs, the SA538 would be a perfect centerpiece for your mic pack. No need to take a bright and a dark mic, because the SA538 can manage nearly any vocalist type. Its sturdy construction (the tube is protected by a rubber guard) makes it suitable for the rigors of the road.
I think having more experience with the mic I might conclude the same , however the vocalist I was working with had a lot of range and different voicings and this mic won out over others.
I dont know if there is as much awareness of this mic as it deserves
Charter Oak SA538 & 538B
These are not the cheapest mics of their type around but, judged on their sound rather than their technical spec or the origin of the parts, they are probably worth the extra cost, as their sound compares favourably with high-end/classic mics costing a lot more, and they somehow help a vocal sit comfortably within a mix without getting buried or being too loud. In this regard, the use of higher quality electronic components certainly pays dividends. Just like the classics they are being pitched against, the noise figures are nothing special, but unless you're recording quieter sounds at a distance that shouldn't be a worry.
So a good all around-er and able vocal mic . not sure of other apps but this mic has a forgiving sonic signature without being overly colored in any direction .
