Reverb idea(most likely already thought of, didnt work well)

[GrooveChampion]

So listening to some demos of the Reverberation Machine I thought to myself, how hard is it to incorporate an octave up(not polyphonic, I know) into the feedback loop of a Belton based reverb for....*sigh* shimmer like reverb?

Disclaimer: I do not actually know how one is supposed to do that or if this is even possible.

The way I would do it is make a feedback path like in the all star reverb or some other reverbs, but make this feedback path accessible for other pedals, and then use a digital octave up pedal in this loop (ps5, behringer US600, ..) It is on my to do list but not right away.

So are there any diy reverbs with an fx loop?
