One of the lessons I have learned withy my BB2 is not to use the hpf on my Mesa 800+. The low bass on this cab is so wonderful that, unless there is a real problem with the room, it seems such a shame not to use it all. For some reason, I currently seem to prefer the BB2 with my jazz and the Four 10 with the precision. Guess I might be subconsciously trying to justify owning four Barefaced cabs, or maybe it is because the single coils on the jazz like the tweeter/horn on the BB2. Either way I am sorely tempted to add a midget or compact to the family, I just cannot decide which would be a better match to the BB2.
