I've placed LPF before my octaves (knowing I have RFE and Messenger downstream, the end basically) to clean up the octaves response/trigger but I don't like to over EQ as well, BUT if they are the same setting, or close it can tighten up the cut. It's when people have completely different EQs all over the place things get messy. I'm trying to reduce the most EQ as I can honestly. Bass is mild, preamp is mild, I would like some pedals that have bright and deep switches though, just that, a couple of foot switches controlling a bright and cut circuit, like the Solarian honestly
