DIY reverb article

For those who are keen to try real DIY reverb, consider this article:

By coincidence, I found and bought the vintage magazine containing this article a few weeks ago, and was planning to scan it, but I've just found it on-line.

Quite interesting really.....
Using record player pups!
Seems like a pretty good idea but, I don't think it could function as a stomper.
Imagine the racket from stepping on the footswitch a bit too hard huh?
I'm interested to see what some of the more experienced fellas think.
If nothing else, it was an interesting read.

Been there, done that

Thanks for posting that.  It looks like a later version of what I was referring to in my post.  What I built all those years ago was a tube circuit based on ECC83's (12AX7),  but the spring unit looks identical.  More modern thinking says that the spring should not just be vibrated but moved in a rotating motion to get best results.  See here:  http://www.electronicpeasant.com/projects/springs/springs.html

BTW, can you still buy ceramic phonograph cartridges?

Gee guys, I never presented it as the best reverb stompbox ever, just something to get the DIYers thinking!

One advantage to using rotational waves on a spring, is that the rotation wave is much slower. I remember seeing a computer memory that consisted of about 6 inches of wire that had a twist mode, back in the 60s.. wish I'd kept it! (it was only a 'memory' if you cleaned up the output & sent it around again, of course).

I'm building one with remote CMOS switching...one box to hold the electronics, then a seperate tank, and then there's a footswitch that activates the electronic switch.

Remember that Joe Meek once rocked the world with a homebrew reverb tank built around a gate spring...

Anyone remember the one that ANSIL made?   Made from a fish aquarium with a sealed mic in the tank on  one end and a sealed speaker on the other end.   
too cool.  I still think one day I will make on of those.  Cool for t he stage, maybe lighted.....

Peace!

I don't know why everyone is worried about the stomp switch generating noise. For one thing, it's common to have an off-board reverb switch. for another, it's a tradition for some rockabilly guys, to deliberately kick the box to get the BOINGGggg...
