Yeah, the Space FX is basic and not great, however it's a super cheap option so I was able to get two inexpensive units to mess around with. I decided to do the Space FX full wet signal on one of them. I was playing around with it over the weekend of feeding the signal of one into the second one then back into the first one. Combined with a VCA I was able to get some pretty fun distortion, mostly combining the Ambience on the wet-dry signal one, then Echo on the full wet signal one. I had a lot of fun messing around with it for a while, but the sheer lack of CV control is the killer. That will make for a future DIY mod for me.
But at the end of the day I get better FX through my mixer / workstation (I picked up an old Yamaha AW16G for cheap and it's filling in a lot of gaps in my setup for the time being). I will probably pop out the Space FX when I can get something better, maybe have a little diy side unit for quick fx hits, we will see.
I appreciate the feedback!
