GK 400RB Line Out ??
I have never used the line out on my 400RB's, usually just run the signal into the direct box, and then balanced from box into the house and 1/4 out from box back to the amp ... but I have been wanting to try it using my direct out on amp (unbalanced 1/4) into the direct box ... almost seems like a silly question, but I am assuming that I use shielded guitar cable for this, and not speaker cable ?? .. thanks
