reverbs

[Milliams]

Does anyone know how to get the "slapback" kind of reverb? The kind that you
hear in Sun studio records? Like Elvis Presley or Johnny Cash? I was listening
to Depeche Mode's "Songs of Faith and Devotion" and they had this slapback in
almost all of their songs. It sounded so right-on. When I worked in radio, I
was able to get some high frequency slapback/feedback. I couldn't control the
rate, though. I don't think this thing is spring reverb. It has to be
something else.
