Hi Sacguy71,
I know it's not a Eurorack module but I love the pedal from Source Audio, it's called the Ventris Dual Reverb, it has a beautiful and good quality sound. It can provide you those nice spacey sounds you were asking for. Since you are into guitar "business" as well, you might want to consider a pedal like the Ventris Dual Reverb.
Kind regards, Garfield.
