UAD’s cheapy/light/downsize version of tape emulation. But wait… it uses the exact amount of DSP resources that the Studer A800 uses. How can that be?
You can take a look at the full UAD 1073 here.
Without the EQ section of the 1073, the preamp has a bit more low end and doesn’t roll off where you can really hear anything. The harmonic/noise modeling seems pretty close between the two plugins, other than a couple of low end spikes in the preamp. (It’s hum, man!)
