Most of the effects in the Eventide pedals are nort available in the H3000 line.
We refer mostly to the H8000 in these fx.
An H3000 won't really provide at the same time the complex fx 2 of these pedals can.
You'd have to at leasy buy an Eclipse. Once all the pedals will be out, you'd need and H7600 or H8000 to get all those sounds at the same time.
So, as you see, they are very convenient.
