I recently acquired a rack mount Behringer MX2200. I have a rack Sansamp RBI and an RMX850. I also run about 5 effect pedals that I run through the effect loop of the RBI. Where in the rig should this go? I've run it through the effects loop along with my other pedals and it's affecting the pedals in a negative way, i.e. greatly diminishing the "effect" of the effects. The Behringer also has a "side chain" which I thought would operate as an effect loop, but really doesn't because the only way I can get my pedals to work in that configuration is to turn the bypass the compression/limiter. What good is that?
