I think all of us are talking in too many general terms. Losing low end around the 100hz section versus the 40hz section - you are going to notice the 100hz section much faster since our ears will pick that up quickly. Depending on on our rigs and how we are using the pedal, it's going to be a different result each time. I believe searching for a overdrive pedal which keeps the low end is frivolous. Get a blend pedal and get ANY overdrive/distortion pedal you want. Make your life simpler.
There definitely could be something wrong with the ODB-3, however, the pedal sounds like midrange scooped garbage in my opinion. At this point, replace it.... However, I should not jump to conclusions so fast.
Was there a phasing issue? Like the board was completely out of phase with your signal and the low end disappeared? The X-Blender has a phase switch which would fix this problem in seconds.
I suggested the X-Blender because modern recording techniques say "two channels for bass" one for effects and one for the clean. That's how you get that heavily overdriven tone mixed in with bone-crushing low end. The X-Blender is the closest thing I have found for two channel sound in ONE bass rig.
