ITS8 Tube Screamer clone not working

[jcwillow777]

Hi:

I am relatively new at building pedals. I have modified several pedals through Indygutarist.com. I have built a few A-B boxes, but I haven't had a lot of luck builing pedals. I am determined to figure this one out though. But,I need a liitle help!   I recently purchased a circuit board from generalguitargadgets.com for a tube screamer clone. The info can be found here:

The bypass switch is working. When I plug my guitar in and the pedal is in bypass mode I get sound throught the amp. When the pedal is on, the LED lights up but there is no sound.

I have done a few modifications. I changed C4 to a 47pf capinstead of the 51pf cap that is specified, simply because I sisn't have one. I also used a mon jack for teh input beacuse I don't use a battery, just a 9VDCS power. I added the AMZ Fat modifications as explained on page three of the modifications pages. Lastly, I put in an IC socket so I can switch out chips. I currently have an OPA2604AP chip installed now.

I have taken a few readings.

D1
A - 4.68V
K - 4.58V

D2
A - 4.58V
K - 4.68V

D3 - 4.58V (jumper)

Q1
E - 8.31V
B - 8.31V
C - 9.03V

Q2
E - 8.31V
B - 8.31V
C - 9.03V

IC1
Pin 1 - 4.58V
Pin 2 - 4.68V
Pin 3 - 4.5V
Pin 4 - 0
Pin 5 - 4.57V
Pin 6 - 4.58V
Pin 7 - 4.58V
Pin 8 - 9,03V

I have also taken readings at all of the capacitors and resistors, I will imput the info if you think that will be helpful. After looking at the instructions page, 3, I see that the readings on the transistors are high, I just don't know what I need to do to fix it.

I made an audio probe, care of R.G. Keen. I plan on using it tomorrow. I am a liitle unsure what to expect. I know that the 1/4" jack plugs into the amp and the shield is clipped to ground and I probe with the capacitor lead. I'm just not sure what I should or should not be hearing so as to know if there is a problem or if it is OK.

A picture of the pedal can be found here:

Thanks in advance for any advice you can give me so I can get this baby up and running.

How is it going, have your pedal working now..?
