Im not sure which one you guys have, but Ive heard there are slight differences in the glowing eyes to the smaller enclosure. Ill also remind you all, I have that FET boost built into mine, and that made a huge difference for me. I still remember having trouble getting the volume I needed out of the BB when I first got it. But I liked the flavor so much and John K had put a boost in his for the same reason, he felt the output was too weak, so I asked him if he could send me one. So he did. And I installed it in mine. And then, there was light.....hehe
I usually set my bass around 1 oclock, drive just past noon, well say 12:30 and then the treble around 9 oclock and the output to the room (which if I put it up to 11 oclock, it is REALLY LOUD at that point). The treble is the only thing I change depending on the bass. But lately I usually leave it where it is and adjust my tone/treble knobs on whichever bass Im using to cut out on the shrillness that can happen with the BB if youre not careful. Part of its charm I guess

I love it, yet I still control it.
Im not sure if you guys ever sent it through an all tube head, but wow, what a difference. I recently took my Electric in for servicing and was using my 1001 in the meantime. It had been a while since I used the GK and it sounded great in the GK. But after about a month, I got my Electric back and had practice and I stomped the BB and was like, WHOA. It sounded immaculately mean and vicious and deep and full and raunchy and saggy and lovely. But overall, I can say with certainty, that the main reason why my BB performs so well in the mix is because of that FET boost. If I didnt have that, I would be struggling IMO and Im not totally sure Id still have it. Ive heard that the newer version has taken care of that by adding more output but it also, from what I hear, differs in tone/sound a tad from the glowing eyes version. Of course this is all hearsay, so I may be talking outta my a**. Anyway, I LOVE MY BB AND IT WILL GO NOWHERE!
