So I got my B2re and so far, it is pretty ok. My initial impression is that you really have to push this amp to hit its "sweet spot". I mean.....2/3 of the way up (volume, gain, tone controls....) is where its best seems to come out. I don't have a good bass driver to put in front, but am using a BBE Sonic Stomp and tried a Behringer BD21 which isn't too bad. the reason I got this amp is that a friend had a tech21 bass driver in front of it and it sounded like a million bucks! this is similar but not nearly there. So.....my question for users of the B2re.... how are you setting yours up? what settings seem to generally work best for you and what toys are you using with it? (and how) I tried my Sansamp RBI in front of it, but I get bad current buzz through the amp - doesn't work. I can use it preamp in.....but I actually like the preamp sound of the B2re. Ideas helpful and appreciated.
