Once upon a time I had access to a huge tube mic collection and I used them regularly. I did lots of orchestral recordings that used an all-tube chain (the Brahms on my webiste is once such recording- Neumann 582s, Schoeps 221s, Vac Rac preamps...)
I used regularly 582's with the gold omni capsules, Schoeps 221A and B, AKG C61, Neumann UM57, Neumann SM69
, SM2 and SM23. I'm sure there are some more that I am forgetting right now... They all had unique sounds, some were nothing short of spectacular for some things and others I could do without.
Today, i will on rare occasion rent U47's, U67's and other mics...
