After trying it out on several sources including drums and guitars, I have to say that Waves has the best 1073 emu I've heard outside Nebula. To me, it edged out UAD and put the old VEQ3 to shame. HOWEVER, I'm spoiled by the Nebula sound, so unless I get tired of using that, I'll keep my AlexB emulations in my projects (his API 550A is my current go-to for this style of EQ). I still may pick up the Scheps when it inevitably goes on sale.
I still use RS56 a lot, and it seems Waves have matched its quality and ease-of-use with this new one. Nice job, Waves.
Cheers,
Eddie
