Seamoon Funk Machine V2 w/ buffered blend doesn`t work!!!

Muffit
Hi,
I just finished up the Seamoon Funk Machine V2 with the buffered blend.

Well, how the header says, iit doesn´t work, there is no sound coming out, but a faint hiss if I rotate the Blend knob towards the wet side.
I trieds to probe it, but I don´t really know if I do it correctly, I get a sound at the Output B (pin 6) of the LM1458, thats it. The side A on wich the NPN is doesnt work.
I measured every component prior of building it and everything was fine.
I checked for little bridges and went over the traces with a knife.

I used LM1458N, 2N5457 for Q1 and Q2 and 2N5088 for Q3.

Here are my voltages:

IC:           Q1:          Q2:           Q3:

1: 4,1       D: 8,3      D: 8,3       E: 0
2: 4,2       S: 7,4      S: 7,4        B: 0,6
3: 4,1       G: 7,5      G: 7,5       C: 0
4: 0
5: 0
6: 6,2
7: 7,5
8: 8,3

The voltages of Q3 look weird, other than that I have no clues what is wrong

Thanks in advance for any help.

Cheers

I probed it again, the weird thing is that there is a Signal at the Output, though its not audible unless I crank my Amp to 11 (:
I dont know what else I should try, I kind of think that the "Blend" part of the circuit is the problem, though I dont know how to check it.

So if anybody could help me I would be very thankfull.

Cheers

Hi,
In the end, did you manage to make it work ?
I built it using the same layout, and i get a sound, but the envelope does not seem to work...
Turning the Frequency pot does produce an audible change, but the WET level is very low, also it seems that DRY signal is still coming through, and turning the RANGE pot doesn't do anything...
I tried with various opamps and transistors, but it's the same.
