Debugging TS9 with clipping switch

[litstalov]

Hi everyone. I've built a TS9 clone but it's not working. Actually, I've built it twice, and both times not working... I couldn't find any mistake in my first build and I measured dc voltages and nothing seemed wrong, so I built the second one with a new stripboard but with the same parts, but no luck.

Following Aron Nelson's suggestion on debugging (http://www.diystompboxes.com/smfforum/index.php?topic=29816.0), here is the information a gathered. I'm going crazy with this one (I know, not being calm is my worst enemy!), so please, please, shed some light on me. Thanks in advance. César.

1.What does it do, not do, and sound like?
It seems that everything works the way it should (level, gain and tone), but really, really low volume. Well, the gain pot does not actually distort the sound when all the way up, but increases the intensity of the sound. Tone really seems ok, and the sweep in the volume pot seems also ok. But everything is very low and undistorted.

2.Name of the circuit
Ibanez TS9 compact with clipping switch (from tagboardeffects)

3.Source of the circuit (URL of schematic or project)
http://tagboardeffects.blogspot.pt/2012/02/ibanez-ts9_17.html (second image)

4.Any modifications to the circuit?
No

5.Any parts substitutions?
No

6.Positive ground to negative ground conversion?
No

7. What is the out of circuit battery voltage?
9.08

Report the voltages as follows:

Q1
C = 9.08
B = 4.60
E = 4.02

Q2
C= 9.08
B= 4.60
E= 4.03

IC
P1: 4.70
P2: 4.70
P3: 4.55
P4: 0
P5: 4.64
P6: 4.65
P7: 4.65
P8: 9.07

D1
A (anode, the non-band end) = 4.53
K (cathode, the banded end) = 4.60

D2
A (anode, the non-band end) = 4.61
K (cathode, the banded end) = 4.53

 voltqges look ok i think...  is ra resistor, from tonepads layout 100ohm or 470ohm ,maybee you put in a 100k or 470k by accident?, i do that all the time, i always assume theres a k afterk everythingk...

Yes, I've done that mistake a couple of times. I'll double check parts values latter this evening. Thanks.

In that layout, there is a cut trace in the 8th row that is hidden by a 510k resistor in the upper view - if you didn't cut that, the input will go straight to the first stage of the opamp rather than through the input buffer.
