I suspect that all wire delay lines were magnetorestrictive, not acoustic. I don't know that.
At one point there were spring based audio delay devices use for adding reverb but they quickly got replaced with memory based solutions when dram started showing up. They weren't spring based, just a loose coil of wire.
Take a look at https://en.wikipedia.org/wiki/Reverberation under Spring reverberators. These are the ones I knew of but there may have been some other devices based on other operating principles. -- Alvin Starr || land: (905)513-7688 Netvel Inc. || Cell: (416)806-0133 alvin@netvel.net ||
