I've got pedals that can suck a bit too much bottom end out the signal (wah, fuzz, env filter) on the A loop of my LS-2...

If your envelope filter is sucking bottom end, replace it, unless it's a high pass filter & that's what you're after.
If it's a low pass, then it's kinda pointless if you're having to put it in a loop.
