Boxed up the Sandblaster fuzz, had some issues first with the jacks shorting out, but a quick rotate fixed that.
It works fine, what I'm curious about from others who have built it, how much of an effect did the buffer have for you? For me it gives a big boost to gain, which I do like, but from a quick look at a demo it doesn't seem accurate to the original. I wonder if I maybe have a cold solder joint somewhere or if it's because I used 2N2222A's for Q1 and Q4? I couldn't find BC182's easily. I'll test some more, check if wiggling the switch makes a difference and maybe try some other transistors (2N5089? I think I read someone suggest that somewhere).
I might also have different gain levels, not 100% sure, and of course that's tricky to check against demos because I don't know for sure how their amps are set up. But I do get a nice range of clean-to-fuzzy, although that's with the buffer switch set to the higher gain position (which one is on, btw? I think I can probably figure it out by measuring it, but if someone knows off-hand...).
