I'm wondering if anyone knows much about this? I was just in the studio messing around with it and found some INSANE noises, but also blew my ears out a couple of times. I'm wondering if anyone has tips on how to be more careful with feedback looping and anything else related to it...

Thanks

Hi WelcomeToTheMachine

I know you only had 1 reply, to this same topic, as the one you posted back in Late Jan 2008.

http://www.bossarea.com/forum/topic.asp?TOPIC_ID=3875

There were about 110 reads on that thread, I guess not many have experimented as you have-do.
Surly someone had some interest or questions.

Perhaps you could expand your description of the gear you used & the effects you achieved.
That might stir up a few more comments.

Were you using guitar-vocals-keyboard, or a noise source?
Any pre. or post processing of the feedback signal?

This is an interesting subject, it's a pity there weren't any reply's.

Regards Dr. Bob

That's funny, I haven't tried feedback looping since I posted that long time ago.

Last night I was playing with a loop I set up on the DD20, and all of a sudden thought about it and decided to try. So I bent down and plugged a patch cord going from B out to B in. As soon as I turned on a delay setting, my lord! This strange but lovely (not to all, I myself am a big fan of Mooger Foogers) noise that kept being amplified more and more with the delay time emerged. I thought hmm, interesting but that's all? No way..

So I plugged B out into my tubescreamer and that into B in, and just to screw with things even more I plugged A out into my pulsar which then went to my amp. At this point I unplugged everything before A in, so now theres an open jack and I'm using the pure noise jumping around inside the DD20. You can get dramatically different effects depending on where your delay time is set, how many repeats you're on and even where your tone is set. It's all quite weird and I still don't really know what I'm doing, but NEVER plug B out into A in. I learned the hard and painful way and almost blew my amp. Maybe I'll try throwing my CS-3 between the DD20 and my amp. It all takes lots of tweaking, the level knob on my TS was acting as some kind of frequency selector and the tone knob was digging up some odd underlying harmonics depending on where the level was set, drive didn't do anything. And then there was the DD20, I had it set on analog, so there was a nice analog decay going along with all this noise. Really cool stuff.

Just wondering - is the analog setting on the DD20 actually analog or is it simulated? Also is there some way to assign an exp. pedal to delay time? Possibly even doing something to select its min and max delay time?

Th analog mode (like the rest of the modes) is all digital, so it's simulated.
The DD7 will be as well.
