I bought a Klangbox Prodyssey for 250 from a forum member, and I absolutely love the way I route it into my hardware mixer. My hardware mixer has the Lexicon Vortex ( Morphing Presets Unit ), the Lexicon Prime Time Model 93, and the EDP.
The Klangbox B4000 goes directly into the Motion-Sound Pro 3t rotary cabinet, but sadly I cannot use Celmo's Stereo EchoRec II.

But it sounds better than it did being routed out of the Scope cards, I am not sure why, other than it has more FAT ?
The Pro-12, and Minimax are great sounding boxes probably, but I found that the Prodyssey has such a different sound. I can't reproduce it's character in ProWave 1.2, or in Solaris 4.1. It responds well to all of my pedals and controllers, and especially the ribbon controller, where I use a tweaked version of the Rich Pad preset to slide up or down to the desired destination.
I only lack a quality spring reverb for the B4000. I am currently searching and reading on pedals ATM. As a last resort a 1U reverb will work, as all of my AUX's in software, and hardware are filled.
I see Soniccore making many ASB's and selling them.
I shall help promote them as much as possible.
