On of your other options i believe would be to run your bass into the compressor helping to even out those note volumes, then into the effects....from there into a limiter to help tame the effects if your finding it hard to balance the levels and then finally into the amp
Dunno how feasable this is but that is how i would imagine it to run if you wanted to really keep your sound tight without having to lose some of the fuzz/overdrives and such which rely on pushing the volume to the valves?
