Title: Guitar sound, at the beginning of "Computer Blue", Prince "Purple Rain" album
Post by: tone seeker on August 22, 2016, 03:28:34 PM
  There is this sound on guitar, at the beginning, and end of "Computer Blue"'.

I've been told it is feedback, but it reminds me of Ibanez AF2, when you turn the Enhance control. It's like a high pitch squeal, that changes
it's pattern, or tempo. I know he used mainly Boss pedals, along with a wah. I just can't figure out what he's doing there!

Any idea's? Link below!

Bottleneck perhaps? Very high, somewhere above the pickups?

Yeah, I could hear some slide in there, but how does it get that ripple squeal sound, right towards the end of that riff?

He was know for doing a lot of effects post production and old tape effects.. might be something sampled and manipulated.

Try to find a live track and see if they get the same effect or if its a backing track. Just a thought.

When in doubt, always go check out a live rendition. That's where the real music is, not studio trickery.

That very well could be studio stuff. I  know he recorded stuff backwards, in many places, from that album.

I was hoping there was some type of effect pedal that could give that
Same random skippy squeal!

prince.org suggests it's feedback coupled with a boss flanger, the silver screw ones from Japan can get a very interesting "pew pew" sound. I figure it's oscillation of some sort.

Thanks for info! I'll have to check out that flanger.
The AF2 Airplane flanger, does some cool, out of sync, kinda sounds like that. I just didn't want to buy the thing!
I would think there would be some way to modify one. That or see what's under the hood of a boss flanger

It's also what I think. You can these kind of sounds running a flanger with lots of feedback into a distortion (or overdriven amp).
