TASCAM Porta 02 MKII Ministudio Multitrack 4-Track Cassette Recorder

Overview

This TASCAM Porta 02 MKII 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, along with the pitch modification in operation.

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.

The headphone knob is a little scratchy.

Pitch Modification

This recorder has been modified with an adjustable pitch knob.

Adjusting the pitch knob will allow you to slow down the recording and playback speed of the cassette. The pitch knob can be adjust so low that the motor stops moving. The knob is pretty sensitive but can produce some interesting results when messed with.

The modification is demonstrated in the attached video.
