I'd have to agree with this. The Strymon stuff all seems to be very cleverly made and scores high points on functionality, but everything I've heard of their's sounds somewhat clinical to me. It's an odd thing, because it's clear they are attempting to emulate analog 'warmth' for want of a better word, but I'm really not convinced they've done it. The other guitar player I regularly work with (who is actually in the band as a backing vocalist who adds some guitar parts) has an El Cap and a Lex. Both leave me cold.
And of course TGWIF is correct, a Leslie simulator is not a Univibe. I wouldn't even consider them interchangeable. The Univibe was a failed attempting at getting a Leslie like effect that ended up creating its own new category, thanks to the likes of Jimi, Gilmour and Trower.
My own choice of Univibe is the KR Megavibe, sadly unobtainium now due to a complete business and ethics failure. I was fortunate to get one in happier times.
Here it is, coupled with a fuzz/overdrive hybrid from the same maker, in my demo of one of the Univibe ubiquitous flagship tunes, Trower's 'Bridge of Sighs.'
