TASCAM 424 MKIII Portastudio Multitrack 4-Track Cassette Recorder
Overview
This TASCAM 424 MKIII has been serviced, cleaned, calibrated, and tested, and is ready for use.
Recording and playback have been tested on all four tracks, and all core functions operate properly. A demonstration video is included with the listing showing recording and playback on all four tracks.
As with any analog cassette multitrack recorder, variations in frequency response and noise between tracks are normal.
The unit is in great cosmetic condition with normal signs of use.
Cassette door on unit is missing
Cassette shown in pictures is not included
Effect sends/returns is very lightly tested. Seems to work but not super thorough (only tested signal passing through both sends from all channels)

Testing
This recorder was tested by recording and playing back an entire side of a cassette tape on all four tracks. This test is performed a minimum of two times, totaling approximately 4–6 hours. During testing, music is recorded in stereo on two tracks at a time, making it easy to compare the recording and playback performance of each track for level, clarity, and consistency (within the tolerances of the recorder). Any issues discovered during testing are corrected before the recorder is listed for sale.
