Try to plug the BE-OD into the effects return of the Micro Dark to bypass the Pre-amp and EQ sections. I used to do this with my drive pedals and I especially love it with my ReezaFRATzitz and Megalith. Limited kasi EQ ng Micro Dark as you may know. And funny thing kasi the EQ setting that I am looking for eh wala sa buong sweep ng EQ ng Micro Dark. Sad lang.
Sa front end naman any EQ would do kasi character parin ng preamp section ng Microdark ang maririning mo. I used to use a Cmatmods Butah and a Berzerker OD. Same sound walang nai-contribute sa character ang OD pedal nag add lang ng gain at compression haha.
Nasubukan ko siya with both options (Effects Loop vs. Front End Input). I seemed to prefer the Front End for this particular set-up. I was going for a boomy sound on the lower strings (something along the doom metal tone spectrum, like Windhand's guitar sound) coming from a '62 SG tuned to C.
Having a compressed pick attack click was not something I needed for the tone, so away it went--maybe if it was shred guitar on a superstrat, I'd then consider changing it over to the effects loop routing.
