AKG D 1000 E by Precision
First of all, this mic is discontinued for quite some time. But so is U47, and no one cares about that if it sounds good. Or great.
This microphone is pretty much similar to SM57, but it hasn't got the fame that SM57 has. Why? I don't know, but it's not fair.
The sound of this microphone is somewhat almost like a condenser, but in a dynamic way. Let me explain this a little bit. It's got more hi-mids and highs that 57, but in a very pleasant way (and not being harsh). Low mids and lows are warmer than 57, at least on the sources I've tried it (guitar amps, vocals and floor toms). And it needs less gain than 57. But the main advantage of this mic is the switch on the bottom: it says B-M-S on it. What it does?
In the B position the microphone has (depending on the speech distance) a bass boosted sound with a linear frequency response between about 15 kHz down to 70 Hz and a bass roll-off at the low end. This prevents transmission of handling or cable noise. In the M position there is a slight increase of response in the presence region between about 5 to 7 kHz. This makes the sound clearer.
The S position causes a remarkable decrease from about 8 kHz downwards which gives a sharper, brighter sound with good speech intelligibility.
As I said before, the mic is discontinued, but you've got plenty of them on eBay. You won't regret this mic, it's a gem on almost everything. Way better than 57!
