Your homework assignment is to find and post a schematic diagram for discussion reference.  |

Do you have some digital pics of the circuit board and ICs thereon?

gfxbss -
I think the digital camera idea is going to be your most expedient option. Fender posts no schematics for pedals on their website...and if it's not in the manual (if you have a manual) it's considered a non-user serviceable part and they probably aren't going to come off of one. But, it might be your best shot...
I struck out at the normal sites and forums too...being unemployed grants the luxury of endless Googling...
Just my 2 cents
Happy Trails

Cyn,
thanks for also looking. i have an email out to fender and am waiting for a response. im guessing that i wont get too far w/ that either.
Chris,
Next time I go to my girlfriends, i will take pics(probably tonight). it is over at her apartment because i spend most of my time when not at work there anyways.
Thanks Again,
Tyler

Hmmm, so you still need to take things there to keep you occupied while you're there? ;D ;D |

sorry, didnt make it over there last night.
she gets upset w/ me because on a lot of nights i give her the option of me working on things at her apartment where she can atleast see me. or me working on things at home ;D
also, she has a couple of computers that i have built for her, however, she has no net.

      hey guys, hope these help. let me know if you need any more..... also, as im sure all of you have noticed it looks like the wall plug jack has been butchered pretty badly. im not sure if this would have anything do w/ it since im using a 9V bat and am still not getting power. thanks again, Tyler |

That jack and the board around it is where I'd start looking. The battery shares those traces, and if something was burned through or lifted, this could be the problem. That jack is probably a switched jack, too. If that switch was somehow wired incorrectly it could be interrupting flow from the battery.
See that diode next to the BNC connector at the top of the first pic? Looks like it says D1. I'm thinking that is a reverse polarity protection diode. It should be wired "backward" across the power supply so that it won't conduct electricity unless the wrong polarity plug is inserted into the power jack. This would be a very convenient place to clip some aligator plugs connected to a 9V DC source. Make sure you identify the + and - on the diode and connect the "wrong" end of the battery. Remember that you probably need a 1/4" jammed into the input jack to get it to light up.

Do you have a digital multi-meter?
If not, can you get one?
