Please find below 2 images of the Pedal

I was able to re-solder new 9v wires to where I believe the old ones were located.
The good news is that there is a phase effect when activated.

The bad news is the clicking sound increases when the pot is turned.

The inside image was taken before I re-soldered the unit.

If there is a phase effect, then I would guess the power leads were placed properly…is that a correct assumption?

If I was wrong…..should anyone be able to point out where the 9v leads should be attached, I would be grateful

Any other suggestions would be welcomed.

We can tackle my 1976 Bass Hoggs Foot next

: ^ )

Many thanks

Bill

I could take a few…how do you post images on this forum?
