Line Level Question

[SpooN]

Probably a dumb question but I am confused.....

I have 3 effects I want to run through my Parallel loop.

Digitech Delay - Digitech Hardwire reverb - Ibanez chorus flanger.

They all have mixer outs, is this where I come out to get them running at Line Level?

disregard I cant seem to get it to work all I get is a high pitched squeal..

Pedals don't have mixer out I must have imagined that :?
