That's correct. RAM was still warming up when I typed that this morning.Not to derail too much, but I was curious about this so I looked at the shcematic, and it turns out it's tweaked xotic BB preamp, which is a tube screamer with a fixed tone control and then a two band EQ after. I can totally see how someone saying its a BB preamp would lead to it being confused with a bluesbreaker. There are a million versions of the BB Preamp from Xotic, there is a cool Aion article about a few versions. The mesa flux drive also took a lot of inspiration from this pedal.
