... Kinda of a tangent for this thread ...
Sorry
to continue on the tangent that Bolo so kindly contributed to .... but here was some more interesting stuff (at least to me anyway) about the "old school" sound from RCA ribbon mics if you didn't see it:http://www.talkbass.com/forum/showthread.php?t=322205
I love the sound of the bass on some of those old recordings.
