I think all of these UAD units are positioned extremely bad (which obviously has got to do with the implementation of things). For live use, you typically either want WYSIWYG access or programmability.
*Check* for WYSIWYG, but in that case, IMO the price can't be justified (and I'd hold any bet that nobody would be able to tell the difference between, say, the UAD delays and any other decent MFX unit in a live context). Seriously, I expect more than 2 FX settings (which are even tough to keep track of because there's no display or any other "parameter value indicator") from a reverb unit setting me short 400 bucks.
And I compared the Ruby and Dream 65 directly with what my Amplifirebox is delivering. Yes, in that case they're delivering more on the usability side of things, but within a complexed pedalboard arrangement, you typically don't need that "more". And once it comes to amp sounds, the AFB IMO is at least on par (and obviously vastly more flexible).
The new pedals are all the way following that concept (or lack thereof...).
Bottomline: Too expensive for what I don't think is the best product philosophy.
But hey, sure, it's now possible to have an all UAD pedalboard. Would not give you presets (well, you can always buy a second Golden Reverberator, can you?), would require an additional loop switcher and a big ass pedalboard chassis, too. On the upside, it could be had for a little below 4k, so that's quite a bargain, isn't it?
