Analog Echo/delay - Is it possible with...

[Brossman]

...Recording wire?

I've been reading about people trying to make some tape echos out of casettes.  To consolidate my understanding, it seems the major problems are:
- difficult/no speed control (unless one wires for a DC motor)
      ** This could be solved fairly easily, but it has been mentioned that the speed increase/decrease will wear out the tape much more quickly
- lack of fidelity
      ** For some of the folks out there, clarity is not what they're looking for in an Analog echo/delay, and rightly so  . ya want some clarity? go Digi... that's not what I'm about with this one.

SOOooo, I just remembered my friend has some old Edison "recording wire" ... I thought it might be able to record short loops.  This loop could be sent through a feeback loop (where intensity (reapeats) could be set), then be blended into the clean tone, producing a short delay/echo.  And...the assumption of the tone quality is quite lo-fi.

Thoughts?

What's recording wire?

Does this friend with the recording wire also have a wire recorder? Does anyone really need to inflict this on themself rather than just using a PT2399?

tape has a cool historical place in this technology, and Some people seek it out like tubes, but reading engineer notes make it out as a nightmare of fix and replace and very poor reliability. There is always the one off story of tape delay lasting or having zero issues, but statistically they are just that.

But a Tape design would be fun if not mechanically challenging.

If you want to say away from Digital, so the PT series chips included you could look at a Bucket-brigade device like the BL3208, I would experiment with two of them to get longer than 102ms...
