I'm really thinking about picking this up soon. I'd prefer to have a Boss ES-8 or Ground Control Pro but they aren't really in the budget with everything else I'm doing gear wise ATM. I already have 2 identical H&K heads to play through(one for gain one for clean) so why not, right? Who's used them? Is there any noticable lag time or added noise involved? I know the ad says a few milliseconds swich time IIRC, but who has first hand knowledge? Is the build quality worth the $260 price tag? Let me know guys.
