Effects that do well in feedback loops?

[FreaqyFrequency]

I am currently thinking about ordering a custom Barge feedback loop in a VB-jr. enclosure, and as I've been simulating ideas in my head, it seems to me that the only effects I can think of that would truly benefit without getting muddy, insanely loud (delay) or introducing other negative side effects would be modulation, such as a phaser or chorus.

In your experience, what effects sound best, or at least better, in a feedback loop?

Flangers. Think the BF-2B is subtle? Not in a feedback loop:

Song of Whale

I knew I wanted a feedback loop. Thanks for that clip.

Can you take one of the Psilocybe, since that is incidentally another effect I'm after?

[nad]

I'd love to, but I ditched my feedback looper years ago.

[FreaqyFrequency]

Build me up just to rip me down. I see how it is.

Thanks anyway for that clip. I'm listening to it for the third time now...it's just brilliant.

That tone is all in the fingers!

[FreaqyFrequency]

Precisely. The fingers are used for knob-twisting, duh!

Generally speaking, all time-based and modulation effects can make some cool and wacky sounds in a feedback loop. Dirt pedals are also cool. I wouldn't think that an envelope filter or octaver would sound too good though, but I've never tried it.

I would think that a tremolo or a rotovibe would be a lot of fun in a feedback loop.

[FreaqyFrequency]

Tremolo was one I hadn't thought of before. Wow...I can't even imagine that.

[TheMutt]

Feedback of a hard chop? If you went too far wouldn't you get either crazy noise or extreme silence?

[FreaqyFrequency]

I have no idea. Until I try it, I consider it as unpredictable as division by zero.

Don't do it! The world will end!
