Needing help dubugging a Rebote 2.5

[Aleenbahia]

Hi there! Total newbie here, this is my 2nd build and (Of course) isn´t working...
It´s a Rebote 2.5, will post the checklist recommended.

1.Bypass is OK, it doesn´t has The delay working, instead it has Noise that increases when moving the Delay or Level pots Up (Clockwise)
2. & 3. It´s the Rebote 2.5 from Tonepad
4.Mods: I used a 5.1k resistor in paralell with a 10k Pot instead of the 15K resistor (Was willing to put a rotary switch with several Resistor values, a mod mentioned on this page, but couldn´t find the switch anywhere!)
5.Substitutions: 56pF Cap instead of the 51pF
6.Positive ground to negative ground conversion? No
7.Battery is measuring 8,4v (It decreased rapidly, as it was almost new) alone, and 7,76V When connected to the circuit

PT2399:
1. 4.99
2. 2.46
3. 0
4. 0
5. 2.98
6. 2.46
7. 3.02
8. 3.10
9. 0
10. 2.61
11. 2.46
12. 1.55
13. 2.46
14. 3.37
15. 0.09
16. 0.09


TL072
1. 4.03
2. 4.08
3. 3.99
4. 0
5. 7.98
6. 3.99
7. 4
8. 3.22

I forgot to measure the 78L05 values, will do...
Also measured the pots, and the 100K (level) is going from 0 to 31.8 and then it goes down to 20.7... I thought that was strange, also read that pin 8 on the TL072 must give same value that what is entering... I assume there´s something wrong there.
Tested another Tl072, same result (Noise, no delay). The PT is the only one I have and I live in a small town in Brasil, no stores around :/
My solding is really nasty, I know, I´m trying to get better, but I couldn´t spot any shorts. I´m posting some pictures, if someone could help me, at least tell where to look?
Also tried to test it with the Audio Probe in the RG page, but I don´t quite understand how to follow the path (It is OK untill some point in which it starts to get nastier, and getting worse after every node...
Forgot to mention: It´s unboxed, but I did put in and out jacks in the box to test grounding issues (Don´t know if that makes sense), also did tested it without the DPDT switch, I connected it to check in and out connections in bypass (It works OK, same results with and without it).
Also please excuse my english

Tl072  pin  5 nearly at the +rail.

Look there?

Thank you for the response! Will check that out and post the results.

Forgot to mention: I don´t have any electric guitar with me, I´ve tested it with a keyboard and an acoustic guitar via preamp (Studio Projects VTB1), don´t know if it may have something to do (Read a lot about impedance and so, but not quite getting it).

That will be fine, as long as you keep the volume low-enough not to clip the input. Even then it'll just be distorted. I'm not sure about the acoustic preamp, but I know that keyboards can get a lot louder than a passive guitar pickup.

TL072
1. 4.03

5. 7.98 ( 8 )

7. 4 ( 6 )
8. 3.22 ( 5 )

The opamp voltages look OK, but your pin numbers are wrong. They're supposed to count up from the bottom on the right-hand side (I've added the correct numbers in parenthesis). Pin 5 (which you have labeled as 8 ) looks low, but that's just a side-effect of measuring it (if you had a second meter, pins 6 and 7 would drop down too when you poke pin 5).

Did you mean pin 8? (The one I counted as 5?) well, I measured continuity in every place near the pins, didn´t get any, even so, did a cut in pin 8 ner the 9v entrance path, just in case. Then this happened:

Yes, I got lost counting!
Now, something strange happened, I think the 78L05 has gone bad... I measured the battery (same one), gave me 9.4V, then I started measuring almost aleatory places (Cause I get lost following the path very quickly), and realised that I got between 9.4 and 8.80 aprox everywhere! in evey pin in LT072 and in pin1 on the PT, the I disconnected, thought that I coud be burning it.
I should get another one, right? (It will take weeks to arrive  )
