My preference for both the behringer clone and the LMB-3 is to have all the knobs pointing north as it is easy to remember and sounds best to my ears. I use a Boss SY-1 synth which I guess is in a similar ballpark to your SYB-5. I have that pedal first in the chain with my thumpinator immediately after, the LMB-3 after that, and then a couple of dirt pedals last. Putting the synth first helped with it triggering smoothly and eliminating glitches.
