Reverb

No threads just on general use/purchase of reverb effect/units.

Tossing up between a Boss RV70 ($149) vs. an Alesis Microverb III ($125) to put in a rack after my sampler.

What should I go for?

neither, use this

Not sure that will fit in my rack.

Got a Lexicon MPX110 of electricsound instead, seems nice.

For reverb / echo I've been usin a Righteous Tones Electro-GLIDE (just a simple tape echo in a digital box, I like it), tho I'm kinda fixated with gettin my hands on one of these guys:

(dude in video kinda needs to stfu and nothin really happens until the 1:30 mark or so, but anyhoo I just really like the sound of it)

For straight reverb I just use in-amp spring tank, I've never liked most of the pedals I've tried.
Had an old '60s stand-alone Pioneer spring reverb unit (um...SR-101 or something like that?) that colored my guitar sound in a kinda weird way that I liked a lot but I had to sell it unfortunately :(

^^I'm kind of a bonehead for old gear.

when I was in college I took a studio recording class, which I failed because I didn't do any of the work and didn't pay enough attention to pass the technical paper tests. Anyway we had an assignment where we were supposed to record something and use several different brands and types of reverb and describe them and choose one. I was sure I wouldn't be able to tell the difference since I have a pretty tin ear, however the Lexicon was noticeably worlds better, so I've always been pro Lexicon.

Until recently when I bought an MX400 which is a really cool unit but doesn't exactly work as advertised. I had to write the company to get a beta version of updated software just to get half of the features they advertise, which still makes it a cool machine, but annoying. It has a USB interface which is good for two things, first, you can edit your programs from software, which is really awesome, second, the editor opens up as a DAW plug-in allowing you to automate changes, but this doesn't really work. It's supposed to be this whole thing where you can set it up so while it doesn't send the audio over USB, if you select the Lexicon as an effect plug-in in your DAW, it knows to route that sound to it and back, and you can then automate. Cool, but I never got the plug-in to work.

Still, it's a pretty kick-ass multi-fx unit and you can edit it with a mouse. It has 4 inputs with lots of routing, 2 stereo effects, or 4 mono effects, though they're more simple. For instance you can have 4 completely separate mono delays going processing 4 different inputs at once. That alone is pretty fucking awesome.
