I'll put mine first in the chain and move my M87 to last. I'm looking forward to seeing what this does for my SVP-CL and VMTD
Wouldn't having a boost before a compressor be a bad idea? I know on the M87 I set the input of mine to a certain spot, however a boost would change the level of the input.
I'd also think you'd want a boost after a filter (if using one) as you've got the same issue with the input. I've found a boost after a filter works great though, allowing you to add something extra to it when needed.
Of course if using the 3leaf boost more for the EQ than boost, than none of that should matter.
