building a spring reverb

[soundsactive]

hey all!

so i have a few different guitar amp spring reverbs and i would like to build a little unit that i can use them for mixing and sending a signal through it. i only did a little bit of research and it seems that there are makeup gain stages after the tank in most schematics. any leads or tips any might have about trying to make this happen?

If you are less ambitious, there is the PAIA hotsprings. There's a kit, but the owners manual on their site and has the schematic, and it doesn't look too hard to perf board. They used to sell the PCB alone, I don't think they do anymore. You get to hack the springs a little bit to wire some kind of out of phase thing. There's no knobs or anything, you use it on an effect send.

There are generalities about driving  springs and picking off the output. Keep in mind that springs are specified or designed specifically for the applications, so a dedicated guitar reverb tank, may not sound very good for full range material even when properly interfaced to.

PS: Let you fingers do the walking but in general springs like to be driven by synthetic current sources, receivers need to be relatively low noise.  Tanks need to be properly oriented wrt gravity, and nearby hum fields.
