Here's something a little different--I recorded it a couple weeks ago...just a compressor, two ODs, a wha and my L6 Echo Park through a feedback looper. Using a wah and my echo park got most of the sounds

Fun stuff. Can you tell us some more about the feedback looper you used? Sounds like something worth checking out.

I found this at beavis http://www.beavisaudio.com/techpages/PedalHacker/index.htm
You might as well build one if you're planning on making a true bypass looper and could spare a 500KA pot

This is a cool idea ... I've thought about just building a wah into a hard shell and swapping the input and output to make teh funneh sounds with my tone knob.

Neat, thanks. I actually have a spare A500k pot sitting on my desk at the moment...now I know what I'll be doing with it. I think it would be fun to replace the SPDT with a momentary switch, so you could bring the feedback in as needed.

Actually, now that I think about it, I might skip the pot altogether and just do the momentary switch...I mean, if I'm going to want wacky feedback sounds, I'd probably want them to be full bore. Then again, it might be good to have a level control in case it's really ear-splitting. I'll have to try it both ways.

This thread inspired me to try and reverse engineer the Ohnoho Chk Chk Boom (http://ohnoho.com/chk-chk-boom/), based on what I saw in the Beavis feedback loop. It's supposed to have the effects loop always engaged, and the switch makes it feed back. Can someone doublecheck my scribbled schematic and let me know if this looks right? It almost makes sense to me, but I could use some help. That's supposed to be a momentary switch there at the bottom. (Kindly ignore the connection I scratched out between the switch and lug 1 of the pot.)



Additionally, I'm trying to figure out how he wires the Loop Mute switch (which mutes the effects loop when the switch isn't pressed, but still gives you feedback when you stomp on it). It's a little beyond me, though...any thoughts?

[lincolnic]

Bump. Does that wiring diagram look right? I would've tried it out already but I don't have any parts on hand.

Really cool clip!

And i will have to build another feeback looper box....

I previously built one like the beavis diagram, with a momentary instead of the toggle, PLAIN AWESOME.

I would strongly suggest adding a switchable output buffer to the feedback loop.

For some effects you don't need the signal to be buffered, but if you're doing some wild delay oscillation and then feedbackloopit, you may explode your amp if it's not buffered...just my opinion....
