Guitarists and studio owners will love this news. If you haven't heard, Michael Fuller (owner of cult boutique pedal manufacturer Fulltone), has created a drop-in replacement for the tape transport mechanism for any tape machine, including the Echo Plex and his own line of machines. This means you can use any tape with your existing vintage tape echo machines.
This is the first time tape echo machines have been able to be used with any kind of analog tape. All you need is your favorite kind of 1/4" tape, some splicing tape, and a splicing block.
