Hello:
I made the post on the POINT TO POINT MUFF FUZZ.
This effect had been in a box for quite awhile. Finally dug it out.
The battery was in it, mistake, and had leaked. Replaced the battery cable.
Now it works in the off position, da. But in the Boost position it acts like a volume control.
NO FUZZ, nada. It has been some time, but I have made circuits like these, but I am not a electrical guy.
The circuit has:
A few transistors.
A few diodes.
A few resistors.
An electrolytic cap.
A few disk caps.

Any idea what might have gotten old.
My guess would be the disk caps.

Could have the leaky battery affected the electro cap, ie reversed polarity?

Any help on what to replace first will be appreciated.

Regards

Paul
