Vortex Sound Research

Didn't know where to look but am open to suggestions for another subreddit that may have a better answer. You can also pm me if you feel this post doesn't really belong on this sub.

What I'm looking for was a tape player that is about as large as a standard portable tape deck but it had interesting functions like playing the tapes backwards, forwards, a crank type feature where you could play through the tape at your own speed.

The reasons I'm looking for this is because I wanted to use it for portable sampling with my small portable setup. Any help would be appreciated.
