For more than 30 years, the Studer A800 Multichannel Tape Recorder and Ampex ATR-102 Mastering Tape Recorder have endured as the world’s most sought-after professional tape recording machines. As two sides of a legendary mixing/mastering coin, the fabled “Studer and Ampex” combination provides the ideal qualities of warmth, presence, cohesion, and low-end punch that only genuine tape can provide.
This is a great video showing how these plug-ins can change your mix. I use these two in my mixes.
That gave me a blast from the past, actually 2. I had a Revox A77 (Studer) back in 1972 that was replacing an older Ampex machine. The A77 is somewhere in the basement still, connected it 10 years ago and got lots of hiss from a tape from back then.
