Hi all!

Got this pedal cheap as it 'didn't work' ==> turned out that the LED resistor was loose. The pedal works fine, just the LED didn't work.
The schematic:
As you can spot it is a Ross Compressor clone; as I marked in RED the changes they made to the schematic. These changes don't sound really good...... my unit was really bright and 'Boring' sounding!!
