Did some small changes recently (added a Blooper looper and swapped the Boss DD-500 with an Empress Zoia). I had the opportunity to test all this out with a few gigs (I comp a improv dance class every month now with a percussion player), and the whole set-up helped me a lot to develop ideas :

For those interested, here's the audio stream:
The stereo output of the stick goes into the stereo sfxsound preamp and then the sfxsound stereo matrix router
Then two parallel lines:
- the low strings go to : Boss SD-2 chain -> Chorus Retrosonic-> Eventide Rose
- the treble strings go to Jacques Trinity filter/wah -> Boss JB-2 -> Keeley Eccos
From there, those two parallel lines enter the Zoia Empress which can do everything: ambient effects, reverbs, pans, filters, mixer, loopers, sequencers etc... all of which can be dual mono to maintain the parallelism of the signals or stereo to mix both signals.
Finally, the output of the high strings goes to a CBA Mood granular delay while the low strings go to the CBA Blooper looper.
Last step, the two signals go to the Neunaber Iconoclast.

I use two different systems as amps, according to the place i gig :
- two Headrush FRFR108 speakers (I have one, the other was lent to me). A great solution for small quiet places or even in larger places as long as there is a sound system that I can feed with the onboard DI outputs.
- for larger gigs/venues, I still use both SR Technology JAM400 and Roland JC-40
