Additional Details


The GX-646 was an auto-reverse,
4 track stereo deck with two speeds ( 3¾ & 7½ ips) and
a whole lot of automatic features including timers, tape bias adjustments,
tape position memory and more.
This was the final model from the 600-series. It replaced the GX-636
and had the capability to use Extra Efficiency tapes (EE).
Other improvements over previous 600 series models were:
“hanging” type VU meters, a three mode timer start switch, and
an additional bias adjustment control on the front panel.
Additional images and a user manual for this recorder
are supplied on the Get Reel Contemporary Classics CD-ROM.

A pretty decent sounding Japanese tape recorder. Some people think it's ugly but I happen to think it's beautiful with some great retro style
