Youtuber LeoMakes has just uploaded a video where he makes his own plate reverb out of some low cost, basic electronics and an Ikea shelf.
Its an interesting idea and responds well to some physical damping.
Here are the parts I used. In case anyone is wondering, I am not endorsed or compensated by IKEA (or anyone else).
IKEA Bror Legs ($16): https://www.ikea.com/us/en/catalog/pr...
IKEA Bror Shelves -- you need two of these ($17 x 2): https://www.ikea.com/us/en/catalog/pr...
A transducer (there are many options; here is what I used): https://www.electrokit.com/en/product...
Two piezo pickups (again, many options; here is what I used): https://www.electrokit.com/en/product...There is a lot more research I would like to do with the selection of transducer and pickups (and probably a lot of other things). If you build one of these or have made your own plate reverb in the past, please feel free to share your valuable wisdom in the comments!
