Burns Buzzaround has a weird attack effect - how?

[BluffChill]

So I've breadboarded a Burns Buzzaround - pretty standard 3 Ge transistor fuzz. I made a couple of subs but it's very close to the original. But I have a strange attack effect - the volume fades in. Does anyone know how this has happened?

I have

Q1. AC128 - not metered
Q2. OC72 hfe43, VF 234mV
Q3. OC77 hfe73, VF 215mV

Video for reference!

I know this circuit isn't supposed to be super susceptible to hfe ranges, but I've tried a bunch in mine, and it definitely doesn't like super low hfe ..   q1 I did like 75 ish q2 85ish and then q3 over 100, I think it was 115.  YMMV

Thanks - the image I found recommended something like 50 for Q1&2, and around 78 for Q3, which all seemed pretty low to me. Strange.

Ac128's are typically pretty high hfe.. I don't think I have one under 75..  may be try that one in q3 and swap the rest back one slot hehe

sounds to me like you're driving the first stage into cutoff, and then its fading in. that's kinda cool, like adding the a leo fuzz to a fuzzface, and you get similar to the old prescription electronics swell fuzz, i forget its name.

i'd either try another q, or keep that one and put it on a switch with another so you can choose which attack ya prefer

OK, looks like I had every transistor round the wrong way!
Now we know

Everyone loves a happy mistake with a happy ending.
