[sdiy] Reverb springs simplified

[John Speth]

I recently discovered a long forgotten OC electronics reverb spring 
assembly in my pile so I thought I'd finally give it a try. Being lazy, 
I just wanted to get something out of it. I was surprised to get good 
results with hardly any effort.

I connected the R channel of my cell phone headphone output to the 
reverb input. I connected the reverb output directly to the mic input of 
an old stereo. I heard the typical spring reverb sound after adjusting 
input drive and mic amplitude levels. It was just a matter of finding 
the right cable connectors, no soldering or additional circuits.

Are typical reverb spring assemblies that simple to apply? I always 
thought there were certain unique drive and recovery circuits that were 
needed for spring reverbs, not attainable without some application 
specific design and soldering. I admit I never studied it closely, I 
just assumed some complexity.

My plan is to use a readily available line level mixer (or mixers), plus 
some outboard EQ to make a flexible spring reverb system.
