Additional Details


Here is an outstanding example of a vintage professional multi-track reel to reel recorder.
Get Reel fan Jens Sundboe from Sortland, Norway (approx 1500 km north of Oslo) has his own vintage home studio and has very kindly sent us pictures of one of his 4-track Studer J-37’s along with some of his observations…
The studer J-37 is the most famous tape recorder ever.  It was used when the Beatles recorded their albums at Abbey Road studios including Sgt. Pepper’s Lonely Hearts Club when they used several J-37’s to create their ground-breaking music.  The J-37 is a beautiful tape recorder.
It’s very heavy (300lbs) and equipped with 52 tubes!
