Vintage 1970s Electro Harmonix USA Black Finger Compressor Effects Pedal *1977*

I recently purchased a big collection of vintage pedals from the long term owner. This is one of those rarities! It is a 1977 Electro Harmonix Black Finger. I've had this serviced by a leading UK tech, and it now plays great and sounds huge! Cosmetically it has been well loved, as you can see. You do not see these in the UK very often so grab it whilst you can! Please see the pictures below as they form part of my description.
