I'm thinking of getting one of these. I borrowed a friends regular BB and really love this pedal. Especially since it has treble and bass controls. Doesn't the A side have a push button switch for 2 frequencies of bass boost. I'm a bit concerned without the bass control I may loose a little of the right bottom end frequency. Unless of course that switch boosts it right.I got one a few weeks ago...GREAT PEDAL! The A Channel is set up pretty much like the original BB Preamp except it has a single tone control instead of treble and bass. The B Channel has even more gain and separate treble, bass, and mid controls...both channels have a switch for soft/hard compression, and you can stack the channels in either configuration A>B or B>A. So many tonal options, it's pretty ridiculous how many different sounds you can get. It also has one of the best finishes I've ever seen on a pedal...burnt orange metallic finish.
