I don't know whats going on. for the longest time I had no issues building pedals. now it's all I'm having.
ok built ts 808 from here http://tagboardeffects.blogspot.com/2012/02/ibanez-ts808.html.
pedal is working but the clipping switch don't seem to make a deference. I have built 3 of these before with no problem. they where all gifts.
measured all resistors before soldering them in. checked for shorts. checked placement of parts. every thing seems ok

9 volt supply

4558
1  4.46v
2  4.66v
3  4.45v
4  0v
5  4.46v
6  4.46v
7  4.46v
8  8.95v

I think this might be a problem the transistors used 2n5088 checked the orientation, it is right the base is higher then the emitter?
Q1
E  3.33v

C  8.95v

Q2
E  3.30v

Umm.. You said that the clipping switch doesn't really work... wouldn't it make sense to have a pic also of your switch..?  :icon_biggrin:

I think I can see in your pics, there is a 47nF cap above a 1M resistor, lower left side. it looks to me the cap is fitted one row high. is this the case?

you are right. fixed it now their is a deference between lift center and diodes but  nothing between led and center
