Got one, aint used it in years. Seemed pretty straight forward, just plug in to INPUT 1 or 2 or both and flip the REC fuctions up or Down to 1, 2, 3 or 4 (only 2 at a time). Then press record. You should setup your mixing first on some dry runs of coarse. It's pretty straight forward, no need for a user's guide. Just keep in mind that recording on to track number 4 actually winds up on the reverse side of the cassete and backwards. Therefor recording all 4 tracks means you can only use the cassete in one direction. In order to get all four tracks back onto one side, you will need to play the tape and mix it out to a different recording source live. Quite often I recorded trax 1 and 2, then rewound the tape and recorded trax 3 and 4. Then rewound the cassette and played the tape live, mixing and panning on playback while I recorded the output to another device.
These days spending $99-1000 gives you a much better digital solution with software on your computer.
Anyhow, good luck.
