Well.
It turns out that it takes some time to perfect the master tape digitization workflow.
Take away: learn how to calibrate your machine. Don't skimp! Buy the calibration tape. Buy the head demagnetizer. Buy the oscilloscope so that you can ensure the azimuth is correct! Just buy the DBX unit!
Make sure your machine is running at the proper speed. Do what it takes to clean the mold off the tapes.
Even so.. I'm only 20% of the way through capturing the 700 West master tapes to 24/192 digital.
The long Winter starts..
