I'm thinking it will have classic compressor types as well as the engine in the UW (if not that on steroids). Imagine SA did to a compressor pedal what they did to envelope filters back in 2011 with the BEF Pro offering 23 envelope filter types with endless backpage options, LFO options, and by the end of a decade, they deliver the Spectrum as an envelope filter that conquers all. And I use it most of the time within just a few presets with any tweaks I really need right there. I think most user friendly SA pedal, also one of the easiest envelope filters to dial in fantastic tones. What they did with the comoressor in the UW left me pleading for the next One Series to be an SA compressor, knowing it obviates the need for the 1176, BBE OptoStomp (the image showed optical, and I imagine SA's optical comp will be as good or better than my old favorite workhorse), Diamond, FEA, Keeley, etc. And when owners of those get the SA, they can emulate their favorite sound and share it with the rest of us to explore; but the likely vast controls will allow even more modification and tailoring to taste. But if it's as straight out of the box solid gold as the Spectrum, SA will have a monster on their hands.
I can't wait for this to happen, partly because I want to use my UW more than as little more than the compressor in the clean sound (with a touch of EQ), and can have this earlier in the chain and the split off for my clean amp signal, which currently just relies on the amp's, unadjustable, built in compressor, so that's a big plus for me and my board needs.
