you know i have seen one somewhere but i can't remember where [ie a replacement] there was a nice little reverb unit that was  about as long as  a hammond D box.  and that got me thinking what about a spring reverb pedal.  obvioulsy there would be noisy issues with stepping on a switch.  and you could kick it an dhave it clang around but some people like hititng there amps to get that reverb sound.  anythoughts

its currently somethign i am trying.
