Non-stompbox vintage effects

Before electronic spring-reverb units, there were mechanical spring-reverb devices...

...necklace reverbs were not any more mechanical/less electronic than Accutronics/Gibbs etc. reverb pans. Principle is the same.

The device I spoke of was not a "necklace reverb" and was not electronic or electro-mechanical. It was a purely mechanical contraption that was mounted in front of the speaker. I was hoping to find a photo or two because it really is a strange-looking thing, but so far I've seen no mention of it anywhere on the web.

You really make me curious about the principle.

I guess not the FR-40 unit?

Not sure this counts in the same way but older records had to utilize making reverb in physical form.

The 6th floor landing in the cinder block stairwell of my college dorm was just perfect for blowing blues harp.

Don't have time to go thru all the posts to see if this one already listed: Klemp Echolette NG51 German tape echo unit.
Every paper-foil cap needs to be replaced and is like a trash compactor in there...typically multiple heads will be open and need replacement. Repair verrrry labor intensive & expensive.
