It works in tandem with the 'blend' function on this pedal - it let's you roll off highs/mids from your clean sound (leaving chunky bass) and filter any messy lows from the distorted sound, so the idea is that you'll get a better balance of the two - fat clean bottom end with big dirty miffed up mids/high end.

That's the idea, but what happens in practice is:
- You end up with less volume hitting the fuzz circuit, resulting in less gain and less distortion.
- The mids and highs are very compressed due to the fuzz but the lows are not. The heavier you play, the heavier the bass, which might be undesirable.
- When you hit that crossover foot switch, expect a volume drop since you are rolling off highs from the clean portion and lows from the fuzz portion.
This was my experience of playing around with the original BBM with an SFX X&M crossover blender. In my experience, this particular fuzz retains plenty of low end by itself. A small amount of clean blend is required to add a bit of definition and dynamics to the sound, but using a crossover did not work out for me. Subtle usage of it though could certainly help situations where you have a high output bright active bass and need to both reduce the clean highs slightly to help the signals mesh together and reduce the bass hitting the fuzz to prevent getting overloaded and mushy.
Still, at least this version has a proper blend unlike the original which requires modding to make usable!
