“Stadium Arcadium” On the solo, we flipped the tape over and ran the sound through a vintage EMT 250 digital reverb, recording the reverb onto a separate track, so that when the tape was flipped back over the reverb would be reversed and begin just ahead of the guitar. Then, we ran the reverb sound through a low-pass filter—which lets you nail any sound down to the tiniest little sliver of a frequency—so that you not only hear the notes coming up ahead of the unprocessed guitar, they are swirling around, and the sound seemingly comes out of nothingness. Also, on the second verse, we slowed down the tape and I picked some triads really fast, then we ran that sound through the EMT 250, which made them sound like futuristic mandolins from outer space.
This quote is from Frusciante describing the recording of Stadium Arcadium.
I think I mostly understand the process, but I have a question on the bolded part. Here's how I figure the basic signal chain goes:
Guitar ------>tape running forward
|
|
--->reverb--->tape running backward
Then, the backward tape is flipped; effect being you now have reverb which plays backwards.
Then combine the tapes, so you have your guitar signal running straight, along with reversed reverb.
This is where I get confused. Assume you've recorded a 10 note guitar riff with this method. Won't the reverb of note 10 be playing when the guitar is playing note 1? (as it's been reversed?)
Hope that makes sense; anyone able to help clear that up?
