Finally broke down, and beta'd up. I'm still waiting on the RV50, and the SVbass, but even they sound better in the highs. In fact, that's been the thing I can say I like most about 18. In 17.xx I found I was cutting my highs from the default settings to make them sound their best, but would sometimes make it hard to make certain amps stand up in the band mix, which made it necessary to make other boosts, and cuts, then tweak a domino of other advanced settings to keep the character in line. Now I find I'm pushing my highs a little up past default, and not touching much of anything else. It's way easier to keep the character I want, and it stands up in the mix without any major tweaking.
