Question about ture-bypass looper

[mbos4115]

My quad true-bypass switcher makes this feedback or constant high pitch noise when engage a high gain pedal, the only way to kinda solve it, is to put my Keeley compressor in the front and it has to be on at all times. Do you guys know a way to get rid of that feedback/ constant high pitch noise?

I'd appreciate it.

Use shielded wires inside the looper.
That's the way to make high-gain pedals quieter, so it also has to help in this context.
I have tried it, and it helps!

so you use the kind you'd use for guitar cables? Or do they make thinner screened wire?

Thanks alot, I just ordered some Teflon shield 20 AWG, hopefully it works.

My wires are 1,6mm thick. So its pretty thin and usable.
