This amp sounds really really good with the unison preamp. I’ve had a real 800RB and it has a warm clear quality that has depth and balls to it like a tube amp. I am kind of shocked at how good the UAD2 amp sounds, I really wasn’t expecting it to sound this good. I put my old amp setting on bass - dimed, low mids - dimed, high mids - dimed, highs - about 10:30, mid scoop - engaged - it’s pretty freaking close. And when I really smacked it with a distressor - it is very metal - and extremely responsive.
It also made me feel kind of dumb - wondering why I accumulated outboard gear instead of getting an Apollo first. The unison preamp really really floored me on this amp. I had a Neve 88m and it sounds good, but the drivers are so bad that I couldn’t really use plugins while recording. This is a 5/5 amp for me and the best bass offering in UAD2 format in my opinion. But I want more UAD - bass players need more love from you.
