Rockabilly Vocal Delay

I don't get into much rockabilly, but from what I remember, I'd set the delay to about 30-50ms, with 0 feedback, and set the L&R the same.
The panning would probably be centred, but that would really depend on how the rest of the project is mixed.
And maybe EQ out some of the lows - those recordings weren't very bassy, were they?

If we're thinking about the same type of sound - my rockabilly years are distant...

ahahahhahaha , i like that. I actually found a plug called Analogic Delay , freebie that I think is KILLER ! and I own Waves and UAD stuff. but this thing beats 'em all.

It usually sounds better in mono I think, but anyhow, if it's mono, set the delay to anywhere from 100 to 120ms. If stereo, set one channel to 1 and 1/2 times higher, thus, if you have the left channel set to 100ms, set the right channel to 150ms, or if the left channel is set to 120ms, set the right channel to 180ms. If you want an authentic sounding tape delay for use on electric guitar, then you'll need a delay that has EQ on it so you can dial out some highs in a gradual slope starting at 2k. If you have a delay like Cakewalk's (I'm using GT Pro so I'm not sure if the delay in Sonar is set up the same) and it has three feedback settings (right, left, and cross), set the right and left to zero and the cross feedback to about 10%. Oh, and leave the LFO settings at zero.

"The question was settings used to get the sound."

Which I gave.

"And who records a lead vocal in stereo? Just because one half of the original mono source is processed through a stereo effect. That doesn't mean the signal is suddenly stereophonic."

Have you ever tried it? I don't know how many times I've stated it over the years here, but I've told a lot of guys who were new to recording and effects that they should listen to a track with an effect on it in mono and then again after converting it to stereo to see the difference. Here's an echo effect on a 30-second mono voice track (George Bernard Shaw giving a lecture).

GB Shaw - Mono

Here's the same track, only I converted it to stereo first and then hit it with delay.

GB Shaw - Stereo

Even though you record something in mono, if you convert it to stereo before applying an effect, you'll get a nice pseudo stereo effect bouncing around in both speakers. (Obviously if you apply the effect before converting it to stereo, and then try to convert it aftwards you won't get the pseudo stereo; it will just sound like mono).

I think that a stereo delay set to an old Elvis slapback echo sounds a little strange bouncing around in the speakers myself. I record vocals in stereo all the time though. If I take a stereo vocal track and apply a bit of chorusing and reverb, I'll get a pretty large stereo spread then compared to mono.

Wow, some great responses. One thing is confusing me, some people have mentioned a room echo. Is that done with mic placement, or are we talking afterwards a very very slight reverb? This is reminding me of a 2 hour discussion I had with a friend last week about the difference between echo and reverb......oh God...............................
