Help with Fender Blender Octave Problems?

[electrogroup]

Hi all,

This is my first official cry for help to this forum, where I've been lurking for quite some time.
I've built 6 or 7 different pedals, with decent results, and thought I'd take on (was goaded into, actually) the Fender Blender.

Unfortunately, I can't seem to get the octave section to produce anything octave-y.
Everything else seems to work just fine (more on that in a minute), but nothing that sounds like the octave sound in the clips I've heard on Youtube.

I'm using the layout and PCB from Fuzz Central with no mods:

http://fuzzcentral.ssguitar.com/blender/blenderpcb.gif

Diodes are 1n34A
Transistors are 2n5089, and I've triple-checked the pinouts and then triple checked the schematic for correct orientation.

Voltages with a 9v regulated supply (putting out a steady 9.45v) are:
          C         B         E       
Q1    4.64    .704     .153
Q2    9.45    4.75    4.19
Q3    6.27    3.72    3.16
Q4    2.68    1.15    0.55
Q5    4.55    0.99    0.39

The  resistors in the octave section are 1%, and are about as accurate as you could hope for. All the caps throughout the circuit are oriented correctly with lower voltage at the negative lead.

I've checked continuity throughout with no problems, and using the diy audio probe method it's getting signal everywhere.

When I hook it up, the Volume and Tone pots (and tone boost switch) work great. The Blend pot works, though from what I understand, it is supposed to mix clean signal with processed. At full counterclockwise, it sounds fairly clean, but as you turn, it doesn't seem to "blend" clean with processed, rather it seems to drop out the clean signal and just increase the processed signal. For all I know, though, this is how the blend knob sounds. Figured I'd mention it in case it's tied to the octave problem.

At this point, I've been through the circuit (and the forums, and the FAQ) a dozen times, and just can't seem to figure it out.
Any help at this point would be greatly appreciated.

Thanks!
