legendary delay that went down in history for being used live in concert by the greatest guitarists in the history of rock (see pink floyd), now still sought after for its unique and special delay effects produced.... this one in particular about ten years ago was completely serviced, all the electrical parts redone, all the rotten cables that were crumbling replaced (typical of this object), capacitors, transistors re-coated, and everything repainted (it looks like new) then left (the studio closed) fully functional... now, after many years, it will certainly still work, but will need, to have the optimal and perfect performance, a calibration ….complete with cables for ready use and a comfortable binson case for protection and transport... object in very good condition with the lowest price ever at the moment....
