Being a newbie, a tinkerer, and one who is interested in recreating "that sound" from the early 60's obtained in some of those great jazz recordings, I have obtained my first really decent microphone; a Stephen Sank modified B&O. It has the sound I want, but the mixer boards I use have too much hiss and not enough gain. As others have noted you need quiet gain in the area of 65dB plus to get good level out of a ribbon, especially if placing in an ambient x-y position. I intend to record live jazz using minimal miking. Can any one suggest a DIY circuit topology that might give me some pre-gain that I might put out there next to the mike? Any thoughts short of spending a fortune on World class dedicated pres? Do I need a tranny if I put the pre near the mike? I see lots of circuits out there, tube, class A, Neve clones, but I was wondering what other ribbon mike users have learned, trying do do it on the cheap.
