Tone Vendor MKI Attack pot not much effect.

Hi,
I just managed to finish MKI and there is a lot of fuzz in it. I modded it by setting a trimpot (20k) for R7. Lowering it gives a sort of dying battery sputter, and 75%+ makes it less fuzzy almost like a boost.
First question/issue is that it has a high noise floor (?), but I was sort of expecting that with fuzzes. But reading other posts it seems to be possible to adjust.
The second issue is that the Attack knob does not do very much. When off or almost off it kills/turns effect off like close to 0 on volume knob. (Which is good and expected) But above 15% it does not do much all the way tTo the top.
I checked the thread by @Coda (MKII issue) but the fix there seems not to be my case at a first glance. Also checked the thread on MKII by @TSReppe .
The transistors from Das Musikding were 1 OC75 and AC125F and AC125U. I tried to compare the hfe on the AC125s but they were very close as I remember.
No idea how to check for leakage and if that would have effect. Musikding are good at sending matched and appropriate transistors imho.
Thanks in advance.
PS I like the casing (from Tayda, long transport...) and knobs combination, will try some decal printing later on.
