Notes	Analog bucket brigade delay. In 15 years of collecting vintage gear i have never encountered another one! Really nice analog sound, maximum delay time around 0.5 sec. Gets pretty grainy and noisy at longer delay times, but in a nice and organic way. Contains 6 x Reticon SAD1024A ! Some gathered info about the M3 brand, from different sources on the net; Music Manufacture Milano. A brand of Caldironi Musica who produced a lot of other stuff like Silversound, Goldsound, Mac, Meazzi, G.I.S.,... and Italian brand from the 1970s - 1981, successor brand of Meazzi.
