They’re pretty, and as someone above said will impress an audience, but in all honesty the quality of the actual FX is pretty crap. I’ve bought them second hand twice in the past (different versions - I’m not totally mental) and become bored very quickly after the initial novelty value wore off, and sold them.

Also they don’t even have balanced connections; if you want to put your whole mix through it rather than using it on a mixer send/return this is asking for trouble really.

Save up for something by tc or similar and a MIDI controller to go with it - pretty much any FX machine will let you control all the parameters in real time.

If you want to do freaky stuff I’d recommend a Fireworx, with the obvious caveat that even second hand it’s a lot more expensive. But trust me, it’s worth every penny. (and you can psychologically make it seem a bargain by comparing the price to Eventide gear ;))
