Like most UAD analog emulation plugins, these are incredibly easy to dial in for great results—especially the G bus compressor. I can't compare them to the original hardware, but that was never a priority for me, and vintage analog gear tends to vary quite a bit anyway.
I purchased this bundle primarily for the G bus compressor, which has since become my first choice on drum busses. The channel strip, which wasn’t my main focus, ends up getting quite a bit of use too. However, the channel strip is more complex and noticeably more DSP-hungry than most other plugins I use.
