Wondering what you guys do? I generally us the 30' rule for my guitar rig.
If it's 30' or less I use the unbalanced unless I start picking up noise. I do this because I don't like the "feel" of the 3dB boost on the balanced. It adds something akin to - but not exactly like - compression that I don't like. It also affects levels between gain and clean. I also get complaints from FOH that my signal is too hot on short balanced cables.
Over 30' I use balanced outputs because I get enough drop in the cables I don't feel it.
Generally they have my guitar rig on two paths of a snake that's 50' or 100' depending on venue.
I've tried setting my rig up with a 3 dB pad when using shorter balanced lines but didn't like it.
What do you do?
