thanks for your reply, unfortunately the LM4562 are not available easily in my country for a fast test, but i had some OPA 2134 and the difference is un significative, same with TL072
i started to check a bit more carefully what i feel
when i activate the compressor i just hear a little bit of high frequency noise around 8K around 4dB so i could that just OCD, i just feels weird at the moment
of course the takes are great and noiseless, now with a good amount of gain and big compression i can go to -90dB of noise, that means absolutely nothing in a mix ....
just feels weird at the moment i press the bypass
i must really give big credit to this build, cause i have different 1176 build at different period and different components inside more or less well calibrated and this specific one ( yours ) is really the most transparent compression that i have heard so far, i mean i can slam vocals as f**k to look like a square and not hear the compression, its magic
so yeah, dont pay attention to my " request " cause its really not significant in the context of music !! thanks a lot for this mindblowing build
