You probably don’t need pre and post trim… if you’re trimming it down you want it pre-eq so that your large boosts don’t clip before you turn it back down, and if you’re trimming it up you want it post-eq so that you don’t clip before your large cuts turn it back down. Well, unless you’re emulating some specific analog circuit and you want to drive it a bit, but the board doesn’t do that right now.
Regardless, it’s a strong +1 from me… I want my eq to function as an eq, not an eq and an overall volume changer.
