I saw this posted local to me so went to see it...


Its a Fender Fuzz Wah from the early 70s. I took a look at some Utube videos before going over. I really like my fuzz pedals and did not even know these existed.

Once there, we noticed that the pedal was not functioning 100% :(

The fuzz is nice but not over the top... when the wah is activated, its sucks the sound and has a very limited sweep… could hardly hear it... :(

This pedal is also a volume pedal but the seller told me had the pedal fixed in the past by CP/CT electronis or something like that in the West Ilsand of Montreal ( don't know them ) and they disabled this function...

So right now, its a fuzz pedal ! lol...:rolleyes:

Based on it being 1/3 the pedal, made an offer that reflected that and now have another pedal to fix ! … :rolleyes:




Any one have one of these ? o_O

They sure didn't make that drawing easy to follow.
A real breeze !!! :confused:

Did find that one wire was on the wrong pin on the volume pot but missing a wire on the out jack !... more digging/head scratching required...

Big Thanks again @mhammer for the plans !!!

I followed the diagram as best I could and with alligator clips figured out were all the wires went !!! :D

The person that did the repairs really messed it up... :confused: nothing went to the volume pot. :rolleyes:

I added the missing wire and rewired everything. that solved the volume control on all 3 function. I then went over all the solder joints and that solved the sag on the Wah function.

The pedal is now 100 % functional !!! :D:cool:

I just need to replace the battery connector since it broke when I tried to remove the battery ! :confused:

It never ends... lol :rolleyes:

If you managed to make the repair using that drawing, you're a better man than I!

One of the interesting features of the pedal is the ability to mix dry signal with the distorted signal.

A lot of it was guess work and common sense. The fact that the pots had solder on every pins was a clear indication that wires were suppose to be there and not all on the same pin... trial and error. The plan showed that wires were connected to all the input jack pins, I just followed the wires.

The fuzz is sublime and mixed with the volume control, a blast to use. This is a very, very good pedal ! No wonder they re-issued it.

Well this is why they say there is no such thing as common sense , figuring that out would not be common for me! Lol

Test leads with alligator clips at each ends are your best friend when trying to fix mixed wires ! ;)

After a while many things DO become "common sense". I discover many solder bridges on circuit boards when I look at pads and traces and wonder "Why on earth would they make THAT trace as complicated as it is, if it was only going to connect up with that other one?" Noticing where connections don't need to be made (but are) becomes a default filter for looking at boards.

Ever watch Mr. Carlson’s Lab?
