Yes. I bent them to see if it would fit.
Well the pins are numbered, does the board or circuit diagram not show which goes where ?

I've looked on the Fuzzdog site, and by the looks of things Pin 1 is on the left.
The only thing to bear in mind is that the trimmer you have is much harder to know where it's set, as it'll be multiple turns from one extreme to the other. (you can hear it click when it reaches either end)
Thanks again chaps.

Pin 8 should be 9V when referenced to ground
pin 4 should be ground ... so measure between 8 and 4 will give 9V
Check that on both opamps
Signal comes in on non inverting input pin 3 .... that will be biased at half the 9v rail roughly so around 4.5V ... so read that between pin 3 and 4 of the first opamp. As a general rule this applies to any opamp used in that config with a single ended supply like a guitar pedal has to use
Check the FET's are the right way round .. this is easy mistake to make
Check any diode is right way round too
Then see what you have
Thanks for this Danny. I've checked the voltage across opamp 1 and have the following readings;
Pin 1 - 4.4v
Pin 2 - 4.4v
Pin 3 - 3v
Pin 4 - 0v
Pin 5 - 4.3v
Pin 6 - 4.4v
Pin 7 - 4.3v
Pin 8 - 9v
Checked the diodes and the FETs and they look right to me. I think I've even got the electrolytic capacitors in the right way this time!
Prod pin 1 of IC2 ... with the pedal turned on, do you hear a buzz ? if so go to pin 1 of IC1 and probe that ... if you have lost it then it's possibly a switch problem, try jumping the switch
Take heart that everyone makes mistakes building these things, I've built circuits I've designed myself and still f#cked up on something silly
Can't work it out. The only thing I get is a short between CI and Ground when the switch is engaged, but that's normal i think?

Fuzzdog ones only go horizontally. I can't see what I've got wrong with the wiring?
(Just as an aside, why do these kits never give you shakeproof washers for the jacks? Or most boutique pedal makers fit them...)
