The original BB Preamp is an immensely popular pedal and heralded as one of the best of all time.
The Custom Shop MB (Mid Boost) edition takes the original BB circuitry but also adds a Mids dial so that you essentially have a three band EQ.
A very useful addition.

The BLACK JUICE PREAMP  takes the renowned BB-preamp to the next level. We’ve supplement the Pedal with a mid-boost control,
adding more aggressive "bite" to your sound and up to +12dB of mid-treble boost. The MB version capable of covering
all the tones that can be obtained with the standard BB Preamp by setting the mid control at 9 o’clock
