This is an original Great British Spring reverb unit from the 80’s, its a classic, and is in perfect working condition. It is (was) for sale, if anyone wants to make me an offer get in touch.
You can see the 1/4″ stereo jack input and output, along with the 5 pin DIN power supply, which is the original and in working order.
You can see whats left of the serial number in this photo, its always been this way since it was bought from a London electronics shop by my Dad.
UPDATE: Its now getting lots of attention on eBay, if your interested start bidding: http://tinyurl.com/45mc85
UPDATE: Its now been sold, quite sad to see if go, but I never really put it to use, so hopefully its new owner will.
