Can you build a spring reverb in a stompbox?

Answer is yes!

I built this one yesterday. Fun build! Thought i'd share since it's something alittle different. :)


My brother works at a recycling station/garbage dump, so he brings me stuff now and then so I can salvage parts like knobs, jack and pots. I found the small spring reverb tank inside an old broken PA mixer/head.

I used the Stage Center Reverb circuit by Craig Anderton to drive the tank. But I wasn't completly happy with the range of the wet/dry controls (not completly dry or wet) so I omitted the buffer part and added a AMZ buffer/splitter insted so I can get it 100% wet. here's the inside:


Only one problem left to solve.. the footswitch. If I had the footswitch on the reverb-box it would make a loud banging noise everytime it was switched on... So I decided to make an external footswitch. However, I didn't want the signal to go through the cabel and back, so I added a small relay inside the reverb box wired true bypass. The footswitch simply breakes the ground connection to the relay (and the led) when turned off.

This was actually my second springreverb build.

I built this one before with a standard size tank in a 19" rack:

It's combined with a Rebote delay in the rack enclosure.

The standard size sounds much better to be honest!

Together with the delay is makes an awesome noise machine. Infinite delay - 100% wet reverb and you'll get very cool organic sounding noise which you can tune by turning the delay-time.

If anyone is interested this is the layout I used:

Not my layout and some things are wrong. Pots are not supposed to go to ground and potlug numbers are wrong, but other then that it works fine. :) Oh, and the Dwell pot should really be a log rev pot.
