so, I have found these pics that have helped a little…

the first is just a hair away from working for me, but the all-white wire color scheme
is a bit frustrating:)

I think i now only need to see where all the input wires go.
the bottom one would work if the wires were color coded or numbered…

nice! thanks-

so- I’ve got that one… the “in” wire.

and so the other 2 points on the 1/4in input jack.. are
power switching?
i am missing those too:(

I can see where the center (+?) on the power input goes to the “AC” pad..
where is that red (-?) going?

are the red and black going to a battery lead?

im grasping to figure this out for a friend… he is stoked at the
chance to use this again after 14 ? years!

thanks alot for your help!!

very good.

and it looks like my stomp switch is missing a wire.
it has one lug on one side going to a trace connected to the “out” pad on the board…
and on the double-lug side of the stomp switch it has only one, going to the “amp” out-jack
the other is missing…
does that go to the final lug on the 1/4in input jack?

THANKS!!!!

alright, so using this pic, L to R jacks and lugs…

correct me where im wrong…

1-“INST” 1/4in in jack
a- to “IN” pad on board
b- to neg (-) batt lead
c- to ground pad / 3rd pot-lug trace

2- AC power jack (pos-inside, neg-outside)
d- to “AC” pad on board
e- to pos (+) batt lead

3- “AMP” 1/4in out jack
f- to stomp switch lug “i”

and then
-stomp switch..

-single-lug side
g- to trace leading to “OUT” on board

-double-lug side
h- to “IN” pad on board
i- to “AMP” out jack lug “f”

THANKS!!

thanks so much for the terrific help…

I dont even own a guitar, so i have only tested this with a func.generator..
but all systems seem go…
from seeing all kinds of big muff schematics.. i decided to get adventurous
and see if i could turn this into a big-big muff by adding 100k pots to the
obvious areas on the board…
I removed the jumper and resistor from the distortion area and added one
and simply replaced the tone switch with a pot…

so does that sound right?

here are some ext. pics
