Make a Spring reverb.

[Thelonious]

Hi,
I would like to build a Spring reverb, with a tank like this one : http://www.accutronicsreverb.com/ Type 4 (or Type 8).
But I don't know how make the input and output amp section. I would like to put all of this in a rack enclosure
If someone can help me, if you have a vero or a shematic for make a spring reverb with this tank, or a original hammond tank (I can have this too).
It's better if it can work with low impedance input, it's for use with guitar, but synth too.
Thanks

Hey I've had an idea of how to do this for some time. You could take the input signal and feed it through a simple LM386 audio amp like the ROG Ruby or Noisy Cricket, whatever you prefer. The output of the amp is connected to a surface transducer or small speaker. This part is physically connected to a spring assembly. On the other end you would have a peizo, or inductive pickup. The output would probably require a preamp, and mix circuit (you can find all of these on the forum) That's how I would build it

Two options come to mind for DIY spring reverb units:

(1) Stage Center Reverb

Vero layout here:

Stage Center Reverb

Should be easy to build.  I'd try this out but I have a 1776 Electronics Rub a Dub Reverb project to do first!

(2) Surfy Bear's FET Reverb

Project here:

Surfy Bear FET Reverb

This is more complicated and there is only the schematic (no vero layout).

Thanks skeletonghost for your tips. But I don't understand why you want to use a piezo or a transducer for the output ?

Until now I used a "dj" mixer for output (phono input it's the good impedance for tank reverb) and a mixing table for input. Works great like this, but now I want to have an amplifying section dedicated solely to the spring reverb.

I'll take a look to your links,  Frank_NH. You're right, the first one is very easy to build. The second look great, and have a tone pot. Not too difficult to convert it to stripboard. But it's a more expensive build.  I'll see this in detail to balance my decision

Thanks for your answers :)
