Feedback looper

[bradfromtampa]

I built a feedback looper pedal from the Beavis audio website.   Everything seemed to work, just the feedback was more of a low rumble.  I was hoping it would be more of a high pitched sound.  I am using a dd-5 in the loop as well.  Is there something i can add to the schematic to change the feedback?

dd5 is delay? put a distortion in the loop without the delay and you will have a nice (or awful) loud high pitched screeching sound. I make a lot of feedback loopers and I get tired of the screech. I made one feedback looper with a really simple low pass filter so I could actually make it do that low drone. feedback loopers will usually get different sounds out of a delay that you havent heard from that delay before. it sends the signal in and out of the delay so its passing the in and out caps and changing impedance as you mess with the feedback on the looper and the volume on the delay. usually the result is your digital delay will sound warmer, like a analog delay or tape delay.

if you really wanna have some noise fun, hook up 10 pedals in the loop

I haven't tried the distortion yet...   I saw a YouTube video for the eye of god and it had the sound I was looking for...  I'm not very technical, so I'm not exactly sure what the sound is I'm looking for, just more high end.....

Oh yes, the dd-5 is a delay pedal.

guys how exactly would you describe the behavior of feedback looper, does it jsut make sound like oscillation or is it controlable with your playing? like if you stop the note will it keep going on or something??

stupid question i guess

Depends what's in the loop and how much feedback you dial in.

Made the russian muff into a sustaing self oscillating muff. It also depends on whats before or after the looper. Humbuckers vs single coils etc.. sometimes you have to dial in the sweetspot on the feedback knob and the gain on the distortion pedal.
