Hi all, there can’t be a better place than this to ask for help with my ‘Little Big Muff’ pedal.
I don’t know much about it to be honest apart from I think it’s from the 1970’s.
The sad thing is it’s not working. I really need to fix this and get it working properly.

I’ve took the back off and there was no battery supply connected. I’ve bought a new 9v battery clip and soldered the red wire onto the AMP output (I assume this is where it goes as there was a small peice of red wire here, looked like it had been ripped off). Is this right? Have I soldered it in the right place? Also, where do I solder the black wire? The circuit board has EH-3003 on it. I’m hoping the only problem with it is the power supply.
I have included a pic of the circuit board.
Any help and advice will be greatly appreciated.
Many thanks.
