Very interesting to hear the difference in the clips. What kind of attack release combo are you using on the compressors? Tempo based or not?
~ 30ms attack, 100ms release, 4:1 ratio. About 3 to 4GR from what I can figure.
I found out how the Overstayer shines, anyhow. It has to be used with its blend knob... so, in parallel. It has a way of sort of rounding out the drums this way without killing the transients. It definitely does not the the pumpy crush crush the GSSL excels at, but it definitely seems to be a different beast. Also appears to excel at mid-range oriented tracks like Rhodes piano, particularly with its Dirt mode engaged.
