Whats the difference in the BSIAB and the BSIAB2?

[sevenisthenumber]

Just grabbed the bsiab from someone on the forum and was wondering how the two differed in sound etc.....

I still havent found the original BSIAB schematic. I'd like to know what the difference is aswell.

I still use my original BSIAB, I love it. I haven't really compared the two schematics as I am completely satisfied with the original one. Why fix something if it ain't broke?   (speaking for myself, not about one circuit vs the other)
