I have been longing to get one of these ever since i set hands on the original BB Preamp. The MB (Mid Boost) sealed the deal for me.
But be warned, This MB model is different from the original BB Preamp. It isn't as transparent as the original. This isn't a bad thing as this MB model has it's own character.
It's mid boost function when tweaked past 1500 hrs can produce some gritty Marshall Plexi like tones. Anything below noon is smooth flowing overdrive.
A little more under the hood!
Not bad at all.....
