I would say that clarity of notes and the SansAmp are opposites.
I have successfully used the SansAmp to tame an overly aggressive pedal.
i agree 100%. i keep my bddi in its own (parallel) loop with most of the treble cut so i can stack another effect on top without losing any low end.
i cant for the life of me use a pick, and i dont go for brand new strings all that often, but that has to be your best bet as far as clarity is concerned. that is not something i have ever looked for in that pedal, just that warm, smooth tones that it does quite well.
my only gripe is that the bypass isnt that great and i get some noise (not a ton, but i notice it).
im not trying to criticize you, but it seems like there would be better choices for an overdrive with lots of clarity.
edit: forgot to address one of your questions.
Also just want to see what else fellow bassists are running with a SansAmp.
as stated above, i run three parallel channels. the bddi gets its own. the octavius sqeezer gets its own. the last one gets a murf, ps3, and zvex machine. some of the wild, synthy sounds can lose the low end, so the bddi is what i rely on for that.
