Description

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. Available in black or silver.

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
